This man is great. Im a sophomore in college and he has been saving my ass on exams since i was a sophomore in high school. He's great for bio and chem too!
Hi I am a Myanmar girl and my name is Elina. I am 16 years old I am watching your videos right now and it is so amazing by your efforts and thank you for sharing your work with us
Watched these videos from u around 8 years back, and now I don’t even know who I was back then. But these videos are still here, feeling nostalgic and little strange being here again.. thanks😊
This man taught this subject to me in 20 minutes( i am including the mirror video) better than me teacher could in 6 hours of total class time. Absolute goat.
ugh im my 2nd year at UCI and this helped me out so much for my physics 52a lab. You were clear and concise in defining what refraction was. your analogy of the marching band was very helpful as well! thanks
Thank you very much!!! I Understood everything in 7 minutes what I didn't understand in a week, literally! Thank you for making these videos😎😎😎. Subscribe instantly to him!!!
Wow even better than my teacher teaches! All my physics teacher does is making us watch a video every day and give us a worksheet in class and don’t even explain or teach how to do the problems and she says her job is to give us the 5 minute video every day and review in clan, but not explain, so I’m like aren’t teachers supposed to teach?🤬 I have the worst teacher ever but this video made mi understand a full week of class in just couple of minutes, thank you
Hello, I have a question, at 6:18 how do you know to draw the second parallel line like that? Like, how far up or down to draw the parallel line? Thanks by the way. You've been helping me through my whole college career (6 years!)
I have a question (and I'm not even remotely prepared to handle any higher math) that will likely be hard to ask and even harder to answer. for context I am a high school drop out with very little knowledge of math. I do however have an imagination and google. So if I want to know what a "rate" is I can google it and learn that it is distance/time and work from there as i try to imagine something like a wheel accelerating and its velocity or whatever, just to give an example. I'm assuming the marching band members represent points along their respective rays and not photons, in the case above, the other closest marching band members respond to the first band member reaching the lens edge by turning toward the edge (ie before reaching the lens edge) is this just something that happened in the animation and not necessarily intentional, or is this an accurate depiction? if so, is this because as a wave it is affecting the light around it, such that at the first point there are "ripples" occurring which slow and change the "trajectory" of the next chosen position of a ray for measurement? I'm not even sure if "ripples" in a light wave can affect other light waves, I unfortunately cannot wrap my head around how something like an orchestra can be reduced to a single wavelength without becoming an average of each part and then sounding like a humm when you replay it, and so it may be that this is beyond my understanding too. but i just thought I'd ask either way.
Mr. Anderson...I am nearsighted, wears glasses... but I think the object that I see is not diminished (or smaller than the real object), why is it different from the concave lenses properties?
wait, sorry, but is the virtual reality of the image creeping up behind you an abstraction of maths, or really Euclidean geometry? ie, can this be done in a real world experiment? Sadly AP wasn't always afforded to me... but thanks for the lesson
Hi Mr. Anderson! Do you happen to have anything on AP Chem? I just graduated from HS and I never took an advanced chemistry class and I want to at least have some extra knowledge before heading to college :)
why wouldn't the ray go through the focal point left of the diverging lens? i know i can always draw three lines to confirm where the image forms. but i have a hard time understanding which focal point to use for different lenses, especially when double optics are introduced
I am a little confused about why the light bends the way it does (or why we draw the arrows the way we do). Based on what I know from refraction, shouldn't the light bend once when it initially hits the lens, and then bend again when it leaves the lens? Why is it bending in the middle of the lens (and only once) where it's not changing from one medium to another?
You're correct, the light does bend twice. He was drawing one bend to make his life easier because he's calculating the total angle of refraction. In reality the light bends when it hits the glass then bends again when goes back into air, giving that total angle of refraction. The way he is drawing it does make it confusing.
YOU TAUGHT IN 7 MINUTED WHAT I COULDN’T FIGURE OUT IN LIKE A WEEK THANK YOU
Same
Same
My teacher's been teaching this for 2 weeks now lmao
Its 10th class topic in India education system
Omg yes I literally sat on my couch trying to figure this out for hours this was crystal clear
I love this man. Seriously was so confused for an entire week, and he comes in and teaches it to me in less than ten minutes.
This man is great. Im a sophomore in college and he has been saving my ass on exams since i was a sophomore in high school. He's great for bio and chem too!
Your learning this in COLLEGE?
@UGHROHA sounds like GCSE
Thanks for making these videos.
Oh my god! It's the legendary Eugene Khutoryansky! Your videos are amazing!!!! Thank YOU for making your videos
both of you ( team ) are also making good....your animated videos are very much helpful
You are the quantum physics gay , I love you'r vedio.

You are an excellent teacher. You talk faster than the rest i have seen but you explain concepts clearly. Thank you very much for all of your work

the analogies used in this videos are extraordinary

Y'all learn this in 2nd year of college? We're taught this in 8th grade 😭😭😭
So lucky
my life just became ten times easier. Thank you so much! I understand this concept completely now
Jasmien Manak Zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
The marching band analogy is just amazing.
OMG that refraction trumpet player analogy/example is legendary, never thought of that that way, got me to understand it better!
I was most worried about ray diagrams for my end-of-year exam... This made it seem so simple. Thank-you!
Hy Cristina its 10th class topic in india education system. LoL
Your teaching skills are so good. My son said he never saw so good physics teacher in China.
Finally understand! I have a test tmrw and this helped ALOT!
I’m studying for MCAT physics and this was the only topic I was dreading. Thank you so much
you taught me what my physics teacher couldn't thank youuu
I had to watch 7 videos before I found one that explained what happens at distances less than the focal length! Thanks!
I couldn't figure out why a virtual image could be on the same side as an object thank you so much for the explanation
your videos and your way in explanation are amazing.Thank you
Hey Love your work, god bless, straight to the point and no meaningless chatter
Thanx!!!! You explained material that on my classes I couldnt apprehend at first!!!
Don't arrest me
You mean comprehend
Visualize the working of convex lens on DESMOS. Its a web based application built for students.

Thanks a lot, perfect explanation, even for non-english speakers!
HOW? He does really explain. what a virtual image is
concise explanation. youre the goat mr andersen!

Mr. Anderson you are a God send.
I'm preparing for the Physics GRE and these videos make for great refresher courses.
I rely on your videos sir. they are very different and so helpful! thank you very much wow
After 3 years of watching your videos, i still call you Mr Bozeman instead of Mr Anderson.🤣
Thank you for making videos like these! I really appreciate it :)
Thank you so much!! I was really struggling, but I completely understand now!! thank you!
cramming for my exams. This is just what I needed thanks man
Great video, I found the diagram of the sliding object particularly helpful. Thank you so much.
Thank you so very much!!! This helped immensely.
Thank you very much! This has helped from failing my exam!
Amazing video. This cleared so much up for me. Thank you!
Simbucket was super helpful!
You are the best :)
I watch your videos even those not in my syllabus
thank you sooo much. I finally know how to properly draw a diagram and i have an exam in two days
super amazing explanation and extremely helpful
This was so helpful man
Amazing! You are the best!
Brilliant tutorial. Thank you, Mr. Andersen.
So helpful
This is for sure my weakness lol idk why just have a hard time understanding how to do proper Ray diagrams cleanly.
This was helpful. Thank you
I watched it before my physics exam...That was helpful.
This video is really helpful to understand ray diagrams. Thanks a lot!
Wait so diverging lens images are always virtual?
thanks. your videos are really amazing, and you use to show how it happens in real life.
Simply and perfectly explanatory. Thanks a lot!
So helpful. Thanks a lot.
By the way...thank u so much for this video, it helps me a lot in understanding the material for the exam of grade 9...👍👍😆
great analogy with the sand!
6:20 can anyone explain what the parallel line is, how do you know where that’s supposed to be
Good video! :)
Yo mahmood what's cracking?
Hello, I have a question, at 6:18 how do you know to draw the second parallel line like that? Like, how far up or down to draw the parallel line? Thanks by the way. You've been helping me through my whole college career (6 years!)
I have the same question lol
Thank you for that video, it helped a lot
Thank you
Very helpful!
you're awesome- thanks for being so thorough!
oh, i understand now. thanks man. i have an exam next week
thanks for the help
Great teacher
well structured
thank you i love this
Very helpful, good information density. Thanks!

guimartgon I hope ur enjoying college
Why can’t we use the focal point in the left for the last example?
hi i am an Indian , IDK about you guys but we have study in class 10th here
so helpful!
I love you sir.
why wouldn't the ray go through the focal point left of the diverging lens? i know i can always draw three lines to confirm where the image forms. but i have a hard time understanding which focal point to use for different lenses, especially when double optics are introduced
6 years later i hope you have an answer for me too
You thought me a lesson that was supposed to be discussed for a week into a 7 mins video
studying MCAT physics using these!
Thank you so much
How do you decide the focal point on ray diagrams ???
this really helped me. Thanks!!
You are a genius
Thank you!!!
I am near-sighted, just learned today that I'm wearing diverging lenses. Thanks.
why does the picture that is seen turns upside down ?
so… anyone here cramming for the ap 2 tmr?
Im cramming tonight for tomorrow lol
AMAZING AMAZING AMAZINGGGGG
wow.amazing thank you.
Awesome
REAL: Inverted, Diminished, forms infront of the object
VIRTUAL: Upright, Larger, Forms behind the object
what simulation software you used?
For the object, does it have to be on 2F? can it be further than 2F?
Is the image is not diminished if the object is on or less than 2F?
Спасибо тебе мой настоящий учитель
Thank you my real teacher
