Physics: Optics- Thick Lenses (5 of 56) Calculate the Location of the Principal Planes

In this video I will find the principal points of a biconvex lens,

Next video in this series can be seen at:

Thanks for the videos, I like them short because info is digested more easily!! But I do not understand how you got the focal length of 10.17?? I'm an optometry student studying for my first round of boards, thanks again!

Thanks! i was looking for what is the meaning of positive versus negative values of h and got it here!

Does anyone know any video that shows the derivation of the thick lens equation?

how i could find the first principal planes if R2 = infinite?

[cuongtrinhngoc]

Sir, how could I find the first point if R2 equals to “infinite”(I mean if the lens it is flat in one side)

[DMG]

Thank you, sir. Could you tell me wich is the name of this ecuation?
Also, what is the focal lenght in this video? Is it te distance betwen the vertix and the focal point or the distance betwen the principal point and the focal point?
Thank you again

Teacher please can you upload videos on Lenses myopia and hypermyopia (corrective lenses)
