[@TheAInfinity]

Thank God I found you. You sir are a hero. You should teach at a University instead of all the professors who pretend to teach, those who go on an on for an hour complicating things and making life harder.

[@stepbystepscience]

Thank you very much for the very nice comment, yes most things can be broken down into simpler steps.

[@TheAInfinity]

Brian Swarthout Just one question sir: at 4:15 you say that di is between C and 2f but how can that be possible? since f = (1/2)*C ==> 2f = C, right? so you're basically saying "di is between C and C." Is this right, or am I missing something? Thank you

[@stepbystepscience]

Al Infinity Yes, you are right, it should say di between C and f. Sorry about that, thanks for catching my error and thanks for pointing it out to me…..that must be a copy and paste error from the convex lenses where it would say the image is between f and 2f when the object is beyond 2f. Again thank you, I will add a note to the video right now.
