I'm in uni taking a physics paper and this is actually the only time i've ever understood nor took interest in optics at all ! Thank you Sal you are awesome
@DalaDos28 I am doing Engineering in the University of Melbourne. I was cramming for physics exam. This Video did help me alot, I got H2B for physics eventhough I was an hour late for the exam :D (the exam was 2 hours long)
Grade 10 science memories. I did terrible in grade 10 science even tho i love science, but my teacher was just too much of an idiot ;'( I love you khan!
Not agree that the real image has the same size as actual object when the object is moved to central point.Because if the size is the same, the triangle that you drew would make the central point not be the twice distance of focal point from vertex. Can you explain it?
Thank you so much, i love you, would you marry me, i am ready, it is the best explanation Ever, end FOREVER, like Beatles or Pink Floyd, I AM YOUR FAN !!!!!!!!!!!!!!!!
having this in university year 1 exam... thanks khan, you saved me days of time.

What's shown here is just a ballpark estimate.
Sal, have you tried using a ruler to draw straight lines? no sarcasm, really :-)
if a virtual image are images that object is not really there, dunno why this is a real image if the object is not really there too :O
I know that feel...
Süper
