Question

The light rays are falling on surfaces $S_1$, $S_2$, $S_3$ as shown in the figures.




The surfaces on which the angle of incidence will be equal to the angle of reflection is/are:

• A. Only $S_1$
• B. $S_1$ and $S_2$ only
• C. $S_2$ and $S_3$ only
• D. All the three surfaces

Answer 1

The correct option is D All the three surfaces

When a light ray falls on a surface, laws of reflection are always followed whatever be the surface.
Therefore, the angle of incidence will be equal to the angle of reflection on all the three surfaces.
