Question

A point object is placed mid-way between two plane mirrors distance 'a' apart. The plane mirror forms an infinite number of images due to multiple reflection. The distance between the nth order image formed in the two mirrors is

Options:

A . na

B . 2na

C . na2

D . n2a

Answer: Option B
:
B
