1:42 to 2:25 best part of the video. The way he explained how its constructive and destructive with his bare hands, deserves an oscar! This stuff went deep into my head! Thanks mate!
I happen to be 'learning' the worst syllabus for AS level physics at the moment (for ages 16-17). The module with all the wave theory and whatnot is very badly presented and indigestable for me. You make it all so clear, I can't thank you enough man, your enthusiam just makes me want to learn!
THANK YOU! I am doing a project on quantum mechanics for my highschool science fair and young's double slit was a part of it. You helped me understand this experiment and I'm not exactly sure I would have otherwise. Once again, thank you.
You are hands down the finest teacher I ever saw. Amazing. I've spent a lifetime learning (BS, MS PhD) and you b-l-o-w away every teacher I ever had. You sir are a master and worth your weight in gold as a teacher
you're probably the best at explaining this topic than any other youtuber. Hell, this was crazy important for me. None of my teachers could do their job right with that. Thanks, really. This was a great help. You're the best. Much love.
He's a fantastic teacher.... I shouldn't say this, but better than my school teacher..... Understood it dramatically.... Its applications..... Mind was blown back in school and in exams....
Hello! Greetings from singapore. I'm a college student and i guess my tutor will be doing this the next lecture. But i guess i understood much more ahead after watching this video. Very very well explained. Excellent. Thanks!
You sir...gonna have a huge contribution in my life...if i ever do anything good with physics your face gonna come and go in ma mind..! Thanks and keep it up..best of luck. No amount is huge enough to repay for the knowledge you have given me. :)
This is great ...the way you bring things together I totally get it. I wish I had teachers like you back in 70s. Definitely, will look for your videos.... Thanks
So does the collapse of a wave function apply additional energy to the photon? I'm trying to figure out if the wave is actually being collapsed into a more dense particle like beam, or if its basically just converting a 3D path into a 2D one. You'd think reducing an entire wave to a particle beam would cause the beam to intensify much like focusing a beam of light or narrowing the exit of a water faucet. Genuinely looking for an answer to this
OMG! how awesome you are! I've read this experiment thousand times in my text book but didn't understand a single word!!and such 9 munites video removed the ambiguity of 6 pages I've been fighting with! you're just one in a million ! I keep watching all your videos and I can tell that I'm making a great progress... thank you for being born!
Light only changes direction if it changes a medium, so nothing crazy, but this is still an interesting thought. If the entire thing's in water, the speed of light is slower, but frequency doesn't change because of continuity. Because wavelength is shorter, that means that 'delta r' (in this video) would be a much smaller number. Ultimately, the distance between bright spots/bright fringes (whatever you want to call them ) would be smaller, and the bright spots would be closer together.
I am failing my required physic class (not related to my major) in my last semester of college. I thought I'd stuck another year of school, but this guy same my butt bumping my final scores to passing! THANK YOU!
since u understoood it can you tell me what the y distance is? is it the distance between adjacent bright fringes? or is it the distance between the bright fringe to the mid point of the slits??
Nice video Is it possible to do a real video using a lazer to show in detail interference not only the interference pattern but also the light through the slits spreading out as a wave?
Don't want to change from mm to nm? Since 1nm = 1 x 10^-9m and 1mm = 1 x 10^-3m Then, Just put y= [(530 x 10^-9)m / (0.1 x 10^-3)m ] (2m) Your result will be in m (meters): 0.0106 If you want your result in cm, then just multiply it by 100 ('cause there are 100cm in 1m)
Please could someone help me? I am told that many laws of "classical" science do not apply at the subatomic level. I was also told that when subatomic particles are smashed together, at near the speed of light, new particles are formed/appear. Do these "new" particles have greater mass than the original particles? In other words, can matter be created at the subatomic level, if enough energy is inputed? Also, what is this lectures full name?
The new particles created after a collision two atoms are actually the atoms' basic parts. What you get are quarks, leptons and bosons as well as some antiparticles (for example positrons). There are even more particles that are created right after the collision but they exist for like very little time. Their mass is smaller than the colliding atoms. The unorthodox laws that you've heard about the subatomic particles is that they don't keep together because of gravity, but because of weak and strong nuclear interaction.
what happens if you put a measuring device and record the electrons going passed the slits, then destroy the recording, will the results show a wave or collapsing wave, as nobody watched the recording prior to it being destroyed, nobody would observed so if it would be a wave, but if someone would have watched after the experiment then future observation can influence the past experiment.
Plotting the Intensity as a function of the angle Theta doesn't actually give the same magnitude of intensity at all bright fringes as drawn on graph. The intensity/brightness is maximum at the central bright fringe, then it fades out gradually as Theta increases along the receptive screen. A literally fantastic video though, dude.
So what about destructive interference? What is "n" is we're asked to find from one minimum to the next minimum? Would n = 1 + .5? What about from central max to next minimum? n = .5?
Very nice :) just wanted to clarify what theta is, since the angle both light waves have to travel at are different, and in the diagram the angle theta is drawn from neither horizontals of the light coming in from the slitsSorry for any inconvenience, but yeah this helped a lot :)
In 1676 a Danish astronomer, Ole Römer, figured out a speed of light from the timing variations of the moons of Jupiter. He figured the observed timing differences were due to the distances across the orbits. In about 280bc Eratosthanes was drinking with a friend who told him that on mid summers day the sun flashed off the water in a deep well in Elephantine, 700km to the South. He measured the midsummer shadow in Alexandria and figured the radius of the Earth within 70km. Some guys are good
for the first example, you got centimeter at the end. how do i know if it is cm or whatever the units? u took wavelengths as nanometers and D as meters...
The video recorder and the light source are using the same electricity power source probably. Thus the light source and recorder are sharing a same informationcommunication channel (the electricity source). Try to use a charged battery powered recorder, this cuts off the information communication channel between the light source and video recorder. Better still, if the light source are also using its own charged self powered different battery source.
u are one epic badass teacher. would hav been fun to have u as my teacher in school. plus, u just cleared up some annoying doubt i had. cheers. from india.
cany anyone tell me what the y distance is? is it the distance between adjacent bright fringes? or is it the distance between the bright fringe to the mid point of the slits??
What happens to the particles that hit the barrier? They whould be bouncing and making another patter somewere else. A patter that is not being observed. And if the pattern is not being observed , will it be afected when the experiment IS OBSERVED?

Great as an introduction video! Splendid job!
Hell, this dude is good.I wish I had a teacher like him.Has he published any books?
Jonathan is author of an applied mathematics book. You can find it here - www.brightstorm.com/teachers
no mathv
I m in 12 nd dis vd helped me a lot ..he explained it very well.....😊😊
Very good lecture. Thank you very much.
Hello! Greetings from singapore. I'm a college student and i guess my tutor will be doing this the next lecture. But i guess i understood much more ahead after watching this video. Very very well explained. Excellent. Thanks!
see his energy while teaching ..soo good..and
power vibes too
You sir...gonna have a huge contribution in my life...if i ever do anything good with physics your face gonna come and go in ma mind..! Thanks and keep it up..best of luck.
No amount is huge enough to repay for the knowledge you have given me. :)

YOU ARE GREAT! I love that you are loud; it helps me pay attention to everything you're saying! Thank you :)
love how enthusiastic this guy is about physics
I am failing my required physic class (not related to my major) in my last semester of college. I thought I'd stuck another year of school, but this guy same my butt bumping my final scores to passing! THANK YOU!

i feel depressed in physics class, but watching your videos has given me some sort of confidence going into physics exams. thanks alot!
2:19 is a great dance tut as well! Many thanks! :D
Nice video Is it possible to do a real video using a lazer to show in detail interference not only the interference pattern but also the light through the slits spreading out as a wave?
Hey Professor Great video. I appreciate your effort. Amazingly understandable
He makes it so interesting and fascinating. My new prof
amazing way to explain!!!! thanks a lot
This guy is simply too awesome!!
Very helpful .. amazingly explained
Really nice explanation, thanks
stressing over finals but Jonathon's here with a good attitude to keep me going at this. This guy is awesome you should hire him to make more videos
Don't want to change from mm to nm?
Since 1nm = 1 x 10^-9m and 1mm = 1 x 10^-3m
Then,
Just put y= [(530 x 10^-9)m / (0.1 x 10^-3)m ] (2m)
Your result will be in m (meters): 0.0106
If you want your result in cm, then just multiply it by 100 ('cause there are 100cm in 1m)
This guy is easily the best teacher on brightstorm.
since tetta is very small, we can use : sin tetta = tetta
it simplifies the calculation
you sir, are a life saver
great teacher
I wish my teacher taught us this way... Loved ur teaching!!
awesome teacher ! just when i needed it thank you!
I think there's a mistake around 6:50 because you said mm is 10^-4, when it is 10^-3 for the first example?
well explained :) thank you Jonathan

it not called central max.m as they all have same intensity.......and thanks for the video it really freshnup my mind...
this videoo is amazingggg..helped a lot
Thanks for watching.
very helpful and easy to follow. keep up the good work :)
Loved his energy. Awesome lecture, man! :)
That makes sense ma man. Get wave distance & you'll get the colour. Kool!!
Tom Winitana Haha it does, eh :D
This guy over here. Thinks he's a scientist :P
what happens if you put a measuring device and record the electrons going passed the slits, then destroy the recording, will the results show a wave or collapsing wave, as nobody watched the recording prior to it being destroyed, nobody would observed so if it would be a wave, but if someone would have watched after the experiment then future observation can influence the past experiment.

Thank you soooo much! This helped greatly!!!
*closer together than if the entire experiment was in air/ vacuum/ less dense medium using the same light source.
thanx! then is there any way to find out the distance between 2 adjacent bright fringes?
Wooow....just an amazing way of teaching ....it helps a lot .....☺😄
Very nice :) just wanted to clarify what theta is, since the angle both light waves have to travel at are different, and in the diagram the angle theta is drawn from neither horizontals of the light coming in from the slitsSorry for any inconvenience, but yeah this helped a lot :)
thank you for examples！
Everything interferes constructively into my brain when this guy explains it.

I love your energy
Thanks! I finally understand it to where I can write my report!
The video recorder and the light source are using the same electricity power source probably.

You are so excellent. thank you, saved me lots of time.
Sinthethta is not equal to y/D
Tan theta is equal to y/D
Great! Thanks for this video!
What a cool teacher. And he looks like Jared Leto.
thanks buddy it was an excellent video
u are one epic badass teacher. would hav been fun to have u as my teacher in school. plus, u just cleared up some annoying doubt i had. cheers. from india.
Thanks Alot!!
Thank you sir!
That's what im talking about!! Just an exercise like the one I had to solve!! Big thanks!
VERY GOOD TEACHER
thank you that was really helpful
@marwakamel17 Y is the distance from axis to where both rays meet for constructive and destructive interference
got an exam in 5 hours. this really helps
Good luck with the exam!
You forgot the loud mouth pop before each "ALRIOT!" Smart guy, but I had to stop watching cuz that drove me nuts.
the first darkspot appears when d sine teta is equal to half the wavelength so why did u half y (fringe seperation) instead of lambda(wavelength) ?
energy
Ecellent and funny. Perfect job man!
Can you plz tell me the main difference between youngs double split experiment and michelsons interferometer
A level physics. I love this man so much!
cany anyone tell me what the y distance is? is it the distance between adjacent bright fringes? or is it the distance between the bright fringe to the mid point of the slits??
You're great thanks
What happens to the particles that hit the barrier? They whould be bouncing and making another patter somewere else. A patter that is not being observed. And if the pattern is not being observed , will it be afected when the experiment IS OBSERVED?
Thank you so much!! :D
thank you! this is so easy to understand! :D
this guy is jus awesome
thanks this is on my physics test tomorrow
U basically are saving my physics mark. Thank you
This guy is crazy awesome!
Thank u
you are the most amazing teacher that I have ever seen =))
What would be the affect on the pattern if the width of the narrow slit is reduced?
This Helped me a lot!!
Thanks :)
best teacher
It was a very helpful :) thank you
thanks finally i understood this experiment, the books aren´t so specific
