'm currently reading chapter 27 of the Feynman lectures, where he derives the thin lens equation for a single refracting surface. He arrives at the equation
h^2/2s + nh^2/s' = (n-1)h^2/2r
Where s is the object distance, s' is the image distance, n is the index of refraction of the second medium (the first is one), r is the radius of curvature, and h is the altitude of a triangle
Where does the (n-1) come from? Wouldn't it simply be n?
This is kind of vague, so please look at the second page of
http://student.fizika.org/~jsisko/Knjige/Opca%20Fizika/Feynman%20Lectures%20on%20Physics/Vol%201%20Ch%2027%20-%20Geometric%20Optics.pdf
I would be so grateful. Thanks.
