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.
LIFE SAVER! I love how you have trouble drawing straight lines, but then you draw the person and it's perfect first try! So funny :p I wish I was an artist!
If there were placed before that mirror an object unlike anything the brain has ever seen a real image of,will it still be able to simulate a correct virtual image?
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
Is it possible to shine a light into a structure that has mirrors pointing to mirrors, etc, etc and for the light be trapped - continually reflecting between the mirrors?
Sal, just a thought that came to my mind. Total number of videos in the library are nearing 2000. We are nearing year end 2010. Wouldnt it be awesome co-incidence to have 2010 th video on 31st December 2010 and 2011th video in year 2011.
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.
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.

I'm really impressed with that face...
"And remember, all reality is just a big simulation going on in our brains." I love this guy.
Remember that for your test tomorrow
That's really tripping tf out... now I can't graduate.....
tripping me*
*Elon musk has entered the chat*
It means like the brain inverts the image formed on the retina.
Image formed on retina is inverted.
Do you also teach Art because holy crap that face looks amazing and u did that like what 5 secs hahaha.
Exactly what i was thinking lmao
And then he throws another bomb a second later!
"All of reality is just a big simulation going on in our brains..." he says, nonchalantly. 😶

proof that MIT math graduates are really brilliant
"..and remember, you know, all of reality is really just a big simulation going on in our brains". He's totally amazing.

I stopped paying attention when he was drawing that face there.
Why was that face drawn SO skillfully....
"Our brain creates a model of this image or whatever."
- Sal Khan
He is an artist as well; respect! I agreed with you.
That reflection of the eye was really cool, never thought of how things reflected.
Was anyone else extremely impressed with Sal's face drawing?
i dont understand how drawing a face is so easy for him but drawing a line is the most difficult think ever :P good job tho
"Now all reality is really a big simulation going on in our brains" ---The Khan Guy. Physics and Philosophy today, is it not?
"And remember, all reality is just a big simulation going on in our brain" Getting philosophical up in this shit hahaha.
1:56 sal why did you have to do that
this is the best explanation online ... killing it as always Mr. Khan!!
If there were placed before that mirror an object unlike anything the brain has ever seen a real image of,will it still be able to simulate a correct virtual image?
'all of reality is a big simulation going on in our brains" whoa.
1:55 "And remember, reality an illusion, the universe is a hologram buy gold, bye!!!!"🔺👁
I feel like I have all the answers, just not in the correct order until I watch your videos. Thanks so much!
a real artist!
sal you're crazy bruh man just drew a perfect face like it was nothing
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
Wow!!! Best explanation of a virtual image yet :D
Is it possible to shine a light into a structure that has mirrors pointing to mirrors, etc, etc and for the light be trapped - continually reflecting between the mirrors?
3:53 i think you should clarify that it's not being emitted from "behind the observer".
otherwise, great vid. very helpful
Thanks guys that's cleared it up a little
Holy crap that drawing of the face looks like a chefs kiss
you've almost penetrate the confusions in my mind
wow this really helped me for my physics exam, as did your other videos!
Sal "all of reality is a simulation in our brains", he went deep on this one
great attempt .best than all other demonstrations.great job
@LAnonHubbard No, mirrors absorb small percentage of light every time they get hit and at light's speed...
God is reflect knowledge 🤔😊
thnxs a lot u helped me a lot for my science exam!!!
sal sir I REALLY LIKE WHAT YOU DO
Sal, just a thought that came to my mind. Total number of videos in the library are nearing 2000. We are nearing year end 2010. Wouldnt it be awesome co-incidence to have 2010 th video on 31st December 2010 and 2011th video in year 2011.
that would've infact been awesome. the real question now is are you still here on youtube (this comment is just a year less than my age.)
Great Explanation Sir Sal! Thankyou for this!
Hahahah "Of course the light is not curvy like that" Love it!!
Amazingly explained. Thanks a lot.
thanks that is really helpful for my physics gcse
ThatMathematicalEngineer how’s life
Thanks ! Sir, I actually got this concept which was too hard for me to get....
Wow, you draw really well.
So helpful. Thank you so much.
Whoa, that was a beautiful face you drew. Man, you are perfect.
Thank you this helped a lot
thank you very much best video
What program did you use to make this video?
Thanks, Sal.
can the book diagram be represented in the same was as the "eye" diagram?
The orange is a lie!
Very nice, very clear. Thank you.
what a great explanation!
thx bro it helped me alot
he is totally amazing
Nice experience
Thanks
thank you again!
I think images in mirrors are flipped front/back not left/right
"THAT IS A MIRROR." I was thinking in perspective of art student lol, no it's a line lmao
thank you
Cool!
My Picasso cannot draw a straight line, but a perfect face in 5 sec!
Sir, but the magenta ray is not falling into the eye.
Awesome video
Awesome
I know right
@NollieSk8 No. You missed. D:
well

@zbe8 Thanks for the answer.
optical illusions
real image can be touched

🤯🤯🤯
Bahahaha I was just about to say that... But so true!! XD
all reality is just a big simulation going on in our brains huh didn't know that I thought I was real lol
jk
@NollieSk8 Damn u lucky.......
American excel!
Why is the sound so horrible that I can't hear normal words?
@sexysadman If you were to key 95/1550 into Google, it'll tell you the answer.
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.
ps. i love your drawing
wat. if the angle of incidence is 0 degree so the angle of reflection is 0 degree also
So reality isnt real. But that's a self defeating statement
what he meant is that the "true" reality isn't really what we perceive as reality
Great face
its so difficult to understand
