CBSE Class 10 Science 2017 · Paper 31(B)/C · Question 32
A student has traced the path of light rays for different angles of incidence. On the basis of observation he must conclude that
- (a)angle of incidence is smaller than the angle of refraction but is equal to the angle of emergence.
- (b)angle of incidence is greater than the angle of refraction but is equal to the angle of emergence.
- (c)angle of incidence is greater than the angle of emergence but equal to the angle of refraction.
- (d)angle of incidence is smaller than the angle of emergence but equal to the angle of refraction.
Answer
(b) angle of incidence is greater than the angle of refraction but is equal to the angle of emergence.
