Surface S3 |
Surfaces on which the angle of incidence is equal to the angle of reflection is/are
पर्याय
Only S1
S1 and S2
S2 and S3
All the three surfaces
उत्तर
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).
