Question

A student traces the path of a ray of light through a glass prism for different angles of

incidence. He analyses each diagram and draws the following conclusions:-

(i) On entering prism, the light ray bends towards its base.

(ii) Light ray suffers refraction at the point of incidence and point of emergence while

passing through prism.

(iii) Emergent ray bends at certain angle to the direction of the incident ray.

(iv) While emerging from the prism, the light ray bends towards the vertex of the prism.

Out of the above inferences, the correct ones are: -

A. i, ii and iii B. i, iii and iv C. ii, iii and iv D. i and iv.​

Answer 1

Answer:

option b

Explanation:

On entering prism, the light ray bends towards its base.

Emergent ray bends at certain angle to the direction of the incident ray.

While emerging from the prism, the light ray bends towards the vertex of the prism.
