Question

A spherical mirror has a radius of curvature of -14 cm. What type of mirror could it be?

Answer 1

Convex mirror

Step-by-step explanation:

Using the mirror formula

1/V+1/U=1/F

Were F=r/2

F=-14/2=-7

So 1/V=-1/7-1/U

Since v=image distance

U= object distance

F= local length

It is only convex mirror that have both local length and image distance negative
