An object is located 25.0 cm from a convex mirror. The image distance is -50.0 cm. What is the magnification?

Given:

Object distance (u) = 25.0 cm

Image distance (v) = -50.0 cm

To Find:

Magnification (m)

Explanation:

Substituting values of Image distance(v) & Object distance (u) in the equation:

-(-50) = 50:

+2

Explanation:

m = -di/do

m = -(-50)/25 = 2
