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

`theta`

`2theta`

`theta//2`

None of the above

Text Solution

Verified by Experts

The correct Answer is:

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

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