A point object is placed mid-way between two plane mirrors at distance $a$ apart. The plane mirror forms an infinite number of images due to multiple reflections. The distance between the first two images formed behind any mirror is:

Options:

Answer:

Solution:

First image behind a mirror is at $a /2$ from the mirror.

Second image behind the same mirror is at $3 a /2$ from it.

Distance between them $= \frac{3 a}{2} - \frac{a}{2} = a$ .
