Question
Light is falling on surfaces S1 S2 and S3 as shown in the figure.
|
Surface S1 |
|
Surface S2 |
|
Surface S3 |
Surfaces on which the angle of incidence is equal to the angle of reflection is/are
Options
Only S1
S1 and S2
S2 and S3
All the three surfaces
Solution
All the three surfaces
Explanation -
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 ail the three surfaces (S1,S2 and S3).
