Question

A student traces a path of a ray of light through a glass prism for (1) different angles of incidence. He draws the following conclusions
(i) Emergent ray bends at a certain angle to the direction of the incident
ray.
(ii) Angle of incidence is equal to angle of emergence.
(iii) Angle of refraction is lesser than both angle of incidence and angle of emergence.
(iv) Light ray suffers two refractions on passing through a prism and in each refraction it bends towards the base of the prism.
Choose the correct observations
A) i, ii and iii
B) i and iii
C) i, iii and iv
D) i and iv

Answer 1

Answer:

Explanation:

Solution

verified

Incident ray and the emergent ray on passing through the prism follows the different path. On Refraction of a ray of light through the prism, the emergent ray always bends at an angle with the incident ray called angle of deviation.

so, correct statement should be "the emergent ray bends at an angle to the direction of the incident ray".

Hence, the correct option is (B)
