I'm looking for someone to clarify a strange result regarding angular magnification. For both mirrors and lens.
m(angular) = θ'/θ
M(lateral) = h'/h = - d'/d
θ ≈ h/d (for small angles)
The Attempt at a Solution
Using the angle equation, I get a result that looks like:
m(angular) = (h'/h) * (d/d')
But since h'/h = -d'/d, I get m(angular) = -1, regardless of the angles, distances, etc. Is this wrong, or is it true that for small angles the magnification is actually always -1?
Thanks to everyone in advance.
