I am doing my science homework about lenses and in class it was so confusing but u were so clear and simple it made a lot of sense
-
Elegant and simple to understand. I hope in the future textbooks will be replaced by good videos like this.
-
Its a great video!

Excellent presentation. In optometry, the converging lens is typically called a "plus lens", and the diverging lens a "minus lens". Thanks,

i have a photography exam on Thursday, concave & convex lenses are going to be in it, Physics ALWAYS confused me, this video was SOOOO helpful thank you so much :D
-
i'm preparing for my physics final and this is so helpful.

How do you create a ray tracing with multiple lenses? For instance, if you had a double convex followed by a double concave followed by a double convex, how would you draw that?

I've got a question: why both sides of the lens, in each case, must have the same shape?
What if you have a plane face on one side of the lens for the incoming light, and the only other one of either the convex or concave type? Would you still get the same results?

Your thinking is correct. The lens does not have to have the same shape on each side. It could be flat on one side, or it could be convex or concave on either side. From what I understand, lenses such as that are common in camera optics.
