Question 3

Light is falling on surfaces $S_{1}, S_{2}, a n d S_{3}$ as shown in the figure.

Surfaces on which the angle of incidence is equal to the angle of reflection is/are
(a) Only $S_{1}$
(b) $S_{1} a n d S_{2}$
(c) $S_{2} a n d S_{3}$
(d) All the three surfaces

Open in App

Solution

Laws of reflection are always followed whatever be the surface of the object. Therefore, the angle of incidence is equal to the angle of reflection on all the three surfaces $(S_{1}, S_{2}, a n d S_{3}) .$
