A light ray strikes a polished metal plate at an angle of $5 0^{c} i r c$ to the normal. What is the angle of reflection?

easy MCQ 1 mark Class 7 · Science · Light

Answer

50°

The correct answer is 50° — Hence the angle of reflection is also $5 0^{c} i r c$ .

Step-by-step solution

The law of reflection states that the angle of incidence equals the angle of reflection.
The given angle of incidence is $5 0^{c} i r c$ to the normal.
Hence the angle of reflection is also $5 0^{c} i r c$ .

Common mistake: Assuming the reflected angle is different from the incident angle
