Question
A spherical mirror is polished on both sides. When the convexside is used as a mirror, the magnification is +1/4. What is themagnification when the concave side is used as a mirror, the objectremaining the same distance from the mirror? A spherical mirror is polished on both sides.

A spherical mirror is polished on both sides. When the convexside is used as a mirror, the magnification is +1/4. What is themagnification when the concave side is used as a mirror, the objectremaining the same distance from the mirror?Explanation / Answer
for convex mirror m=v/u=1/4=f/u+f=R/2u+R so u=3R/2 substituting the value of u in the below equation we get for concave mirror m=f/u-f =R/2u-R=R/2R=1/2
