Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We’ll start by looking at motion itself. Then, we’ll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you’ll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

Great Explanation Sir Sal! Thankyou for this!
So reality isnt real. But that's a self defeating statement
thank you very much best video
Nice experience
Thanks a lot sir.you have cleared my doubt by example of orange.thanks a lot🙏🙏🙏🙏🙏🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳
Sal "all of reality is a simulation in our brains", he went deep on this one
Great face
Awesome
Hahahah "Of course the light is not curvy like that" Love it!!
"THAT IS A MIRROR." I was thinking in perspective of art student lol, no it's a line lmao
plane mirror always form virtual image but when we reflect sun's rays on a wall we get a real image that can be obtained on screen such as wall . how this is possible? kindly clear my dout.

this is the best explanation online … killing it as always Mr. Khan!!
Ooh u drew that face in 5 secs it is awesome
My Picasso cannot draw a straight line, but a perfect face in 5 sec!
I'm really impressed with that face…
I can't able to understand him it's all rubbish
My new PHYSICS SOLVING APP.More then 150+ formulas,Solves for any variable you want,Covers up all physics.download now.https://play.google.com/store/apps/details?id=com.physics.lenovo.myapplication
If you don't understand then you are an Idiot,seriously
Thanks, Sal.
1:56 sal why did you have to do that
aise padhayega to fail ho jayenge
..
Awesome video
theres something wrong with the last part. you broke the law of reflection: angle of incidence is equal to angle of reflection in plane mirror. people might misunderstood that a plane mirror can bounce back to itself but no. you should have drawn a concave mirror to better understand.
Amazingly explained. Thanks a lot.
thank you again!
"And remember, all reality is just a big simulation going on in our brains." I love this guy.
can the book diagram be represented in the same was as the "eye" diagram?
its so difficult to understand
"Our brain creates a model of this image or whatever."

Do you also teach Art because holy crap that face looks amazing and u did that like what 5 secs hahaha.

You are a rebel, i like you
Thanks ! Sir, I actually got this concept which was too hard for me to get….
if only one light ray is coming from that arbitrary point as u said and after incidencing on the mirror if the reflected ray is produced backwards will it still form the image or not
Thanks guys that's cleared it up a little
These are great but please stop repeating yourself when you say one sentence
"Now all reality is really a big simulation going on in our brains" —The Khan Guy. Physics and Philosophy today, is it not?
I stopped paying attention when he was drawing that face there.
I think images in mirrors are flipped front/back not left/right
thnxs a lot u helped me a lot for my science exam!!!
I feel like I have all the answers, just not in the correct order until I watch your videos. Thanks so much!
Why is the sound so horrible that I can't hear normal words?
Sal makes drawing that face in about 5 seconds look way to easy. Try drawing it yourself. I tried to copy his it took me 10 times as long and doesn't even look as good.
