Question

a concave mirror producess 3 times enlarged image of an object placed at 10cm in front of it calculate the radius of curvature of the mirror

Answer 1

The mirror produces three times enlarged image.

So, magnification(m) = 3

WE KNOW, magnification of spherical mirrors = m = -v/u

Where v is the distance between image and mirror and u is the distance between object and mirror.

Here, u = -10 cm

=> 3 = -V/-10

=>v = 30
