Question
A ray of light incidents on a plane mirror at an angle of 30°. The deviation produced in the ray isSelect an answerA30°B60°C90°D120°
Solution
The deviation of a ray of light incident on a plane mirror is given by the formula:
Deviation = 180° - 2i
where i is the angle of incidence.
Given that the angle of incidence (i) is 30°, we can substitute this into the formula:
Deviation = 180° - 2(30°) = 180° - 60° = 120°
So, the correct answer is D) 120°.
