## Homework Statement

I'm looking for someone to clarify a strange result regarding angular magnification. For both mirrors and lens.

## Homework Equations

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.
