Two plane mirror `M_(1)` and `M_(2)` area inclined at angle `theta` as`
` shown. A ray of light 1, which is parallel to `M_(1)`strikes `M_(2)` and after two
reflection , the ray 2 become parrallel to `M_(2)`.Find the angle `theta`

Text Solution

Verified by Experts

Different angle are as shown in figure .In triangle ABC,

`theta+theta+theta=180^(@)`
`theta=60^(@)`.
