In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

what an effective video! its at a steady pace which makes it easy to learn and the explanation is crystal
This is still helpful 6 years later. Thanks!
Best video ever!!! Thank you so much for helping me clear up my doubts! Initially, I was confused whether my understanding about the gap being the same size as the wavelength, but the video cleared everything up! So it literally meant that if the gap was = to lambda then true diffraction (like the ones with a lot of bends) can be seen!
Now this channel really explains DIFFRACTION that is easy to understand. Thanks and KUDOS!
I could not thank you enough! Thanks so much :)
Excellent! I was confused and was sitting idle for half an hour trying to figure it out and my search results weren't helping.
Thank you, Mr. Bozeman
man u r mind blowing ...small video but enough ti give an idea about what it is ....fantastic
You're telling me he teaches this good without us paying him anything and then there's our teachers...
He is paid. Probably got a couple grand for this video.
"Without us paying him"@@yeetusfeetus7877

Why does the wave diffract so big when the gap is smaller than wavelenght? What is the connection between gap and wavelength? Why it is like that?
0:40
@@nicholasdsilva1832 excuse me it is clear that diffraction is greater when the slit size is near to the wave length but how is that expained ?
@@ahmedibrahim-qg3nq i'm also confused about this, is some of the wave reflected under this condition...?
@@jackwilliams4188 Remember the Huygens's Principle - each point on the wavefront act as a new source of wave itself.
What if due to multiple points in the slit region, the waves interfere with each other destructively and only a small number of them are constructively interfered?
1:58 what you seem to be saying is that with a tiny enough slit in the wall, you will be able to see the light coming through it even when standing completely off to the side, adjacent to the wall.
Raphi Stein I think you’re right but it would have to be an incredibly tiny slit
you solved one of my biggest question that i have from past one weak.
thank you so much sir
How on earth!!! My teachers used up all my pages to draw god knows what! N u just write down 4 words! N I understand EVERYTHING! THIS IS VERY VERY VERY HELPFUL!!!!
Great video.... really clear and thorough...thank you for clearing up a great and interesting concept
When i watch this i understand ...Thank you so much
super helpful even after 9yrs....thanks and Kudos
THANK YOU for saving me throughout my university degree, and explaining things in a very EASY to understand-way, unlike my actual teachers😂
where was this channel from long time ago this is amazing explanation thank you so much that was helpful Iam an AS-LEVEL EDEXCLE STUDENT AND THIS HELPED VERY MUCH THANKYOU AGAIN
Thank you for making it simple to understand.
Simple, yet very helpful!😊
Thanks
I have understood what is wave diffraction. You are genius
Great video i really hated diffraction when i was at school thanks for the explanation
Very, very helpful man. Wikipedia has got nothing on you.
You just nailed it ! Awesome and thanks
Noice Video. It may have been short but defiantly got the message threw.
Great video for my Physics activity! Thanks
really helpful...great service to science learners...keep it up!!!
just what needed...thanks
Would also be helpful to understand the amplitude or intensity of the waves at different points around a corner or on the other side of a small opening.
Sorry to be so offtopic but does anybody know of a way to get back into an instagram account..?
I stupidly forgot the login password. I would love any tricks you can give me
@Brantley Grey Instablaster :)
@Arlo Dane i really appreciate your reply. I got to the site thru google and im in the hacking process atm.
Takes a while so I will reply here later with my results.
@Arlo Dane it worked and I finally got access to my account again. I'm so happy:D
Thank you so much, you really help me out!
@Brantley Grey You are welcome =)
that was very very helpful, thank you
wow nice work i totally clear with difractions thanks
This video was helpful, thanks a lot!
exactly the information I needed. Thank you!
So good, now i ´m undestand about the photographic. Thanks.
This video helped me so much. Nicely explained
Too good an explanation Sir. Very helpful. Thank you!
thank you, this is helping so much on my research
Ohh so the diffraction is relative to the obstacles and openings! Meaning certain setups can eliminate any "(pen-/ant-)umbra" as it were! Very interesting.
Thank you so much! Finally I understand it!!
That was awsome!
Your videos are amazing thank you a lot
Thank you so much! This helps alot!
Thank you for making this video. 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Thank a lot Sir. Helpful.
Awesome video you explain it so clear
Excellent explanation thanks a lot
Thanks for the video. That was helpful (Y)
Thanks! Very helpful for my physics class!
thanks sir, it's very helpful
I finally get this shit, thank you.
Got a question how does the size of gap effect the amplitude
My man Carl Fredricksen out here teaching straight facts yo
Yes, very helpful! Thank you!
thx a lot sir, the video was very helpful.
Amazing video. Very objective and clear. Thanks Bozeman.
you are better than my teacher thx
Wow I have learnt more in 4 minutes than reading through a physics book for twenty minnutes
Thanks for your videos , you should put the link of the PHET simulator to experience and play with it , seeing from Colombia
WONDERFUL VIDEO
Thank you for your videos! You're awesome and always clear up questions that I have. :)
yes! that was really helpful.
Really great video ! Physics is amazing, and all these amazing videos available today ! Thanks for that !
Beautiful ! Thank you ! Very helpful
It was really helpful
doesn't actually explain why the waves diffract.
Yes. I'd like someone to explain that to me. It wasn't clear in physics class, and it isn't clear in this video.
Waves cannot particularly pass through a solid object, its like you putting water bucket ontop of your head , the water doesn't go through you, it goes around you. This is why the waves are taking every route they can (the gaps) so the smaller the gap, the larger the rate of diffraction as its much tighter than therefore diffraction is much tighter, hope this helps, hfhf!
no, that's not true that the smaller the gap the more diffraction there is. When the gap is the same size as the wavelength is where the diffraction is largest, anything smaller or bigger is going to have reduced diffraction
Aweri Blakely there might be some calculations but i need to clear it practically
diffraction is just a bending of light. furthermore it shows light do not travel in straight line ..if it would have it would have passed straight from the slit instead of making those curvy waves
thank you, sir
you sir, are a god
Can you please explain why does the wave diffract?
thank you, you saved my physics degree
Thank you Sir
That was really really helpful ... Thanks ❤
this was very good.
awesome!!
What happens once diffraction grating is smaller than the wavelength?
perfect!!!! Awesome video helped a lot :)
This doesn't look like bringing around corners. Looks like a part of the wave that's already traveling on that direction are slipping through and continuing their pattern
U r the best, thank u
king regards
Thank you so much
So helpful, love it!
You're a damn legend
you're wonderful :) thank you!!!
can someone please explain the relation of wavelength and the gap. It makes more sense if it was amplitude. im confused
Good..
Thanks
that was realy helpfull thank u sir
may i know is the degree of diffraction affects the amplitude also?
excelent video. u r the best
Thank you vert Much !!!
Helpful!❤
Great vid
thank you sir
I think these curves in waves appear because the ends of each wave lose kinetic energy, therefore moving each part of the wave moves at different speeds.
Now, in the case of light, this still happens, but light doesn't bend. So what causes this.
Correct me please.
Damn that explanation is so good.
Why is wave diffraction important? Do we currently have a use for wave diffraction?
thank you
Really helpfull nice video
thank you very MUCH!
Perfect
Thank You!!!
thanks bro
I will definately trust you on physics because you look like the eipstein island guy
