A mirror is inclined at an angle of `theta` with the horizontal. If a ray light is incident at an angle `theta` as shown , then the angle made by reflected ray with the horizontal is

Options

A. `theta`
B. `2theta`
C. `theta//2`
D. None of the above

Answer

D

Explanation

(d) we have, `90^(@)-theta+2theta=90^(@)`

`therefore theta=0^(@)`
Angle of reflected ray with horizontal = `90^(@)-theta=90^(@)`
