Homework Statement
Its not a specific question but a general one to solve similar questions. I need to find focal length of a lens silvered at one face
Homework Equations
The Attempt at a Solution
I know a convex lens silvered at one face will behave as an effective concave lens. But i need to find the equations. I can do it by individually solving each case but need a faster one.
My book says that the effective power, P = P(L) + P(M) +P(L)...P(L) is power of lens P(M) is power of mirror. I don't know why this works?
For two lenses kept close i understand why P = P1 + P2 but don't how this works in lens-mirror case too.
Any Help?
