Question

An observer moves towards a stationary plane mirror at a speed of $4m{s}^{-1}$. The speed of image with respect to mirror is :

• A. $4m{s}^{-1}$ towards the mirror
• B. $8m{s}^{-1}$ towards the mirror
• C. $4m{s}^{-1}$ away from the mirror
• D. $8m{s}^{-1}$ away from the mirror

Answer 1

The correct option is A $4m{s}^{-1}$ towards the mirror

When an observer moves towards a stationary mirror at a certain speed, his image will approach towards him at the same speed.
