Application +4 | -1

When an object is at distances of

u_1

and

u_2

from the poles of a concave mirror, images of the same size are formed. The focal length of the mirror is

View answer and explanation

Correct option: C

\left|\frac{u_1+u_2}{2}\right|

Option C,

\left|\frac{u_1+u_2}{2}\right|

, is correct because it represents the average of the object distances, which corresponds to the focal length when images of the same size are formed.
