Question 141: Ray Optics

Question

The focal length f is related to the radius of curvature r of the spherical convex mirror by :

Accepted Answer

For convex mirror, the focal length (f) and radius of curvature (r) are related as $$f =  + {r \over 2}$$.

Answer

f = r

Answer

f = $$-$$ r

Answer

f = +$${{1 \over 2}}$$ r

Answer

f = $$-$$$${{1 \over 2}}$$ r
