Question

3. See the adjoining figure and then answer
the following questions:
(a) Which phenomenon is being represented by the diagram? Define it.
(b) Mark incident ray, normal and refracted ray.
(c) What are the values of angle of incidence and angle of refraction?
(d) Out of media A and B, which media is
optically denser and which is optically
rarer? Give reason.​​

Answer 1

Answer:

Hay friend here is your answer..

(a) The represented phenomenon is Retraction of light.

Defination:Refraction of light is the phenomenon of change in the path of light in going from one medium to another. In going from a rarer to a denser medium, the ray of light bends towards normal and in going from a denser to a rarer medium, the ray of light bends away from normal.

(b) You have already marked.

(c) Angle of Incidence=45 degrees.

Angle of Refraction=30 degrees.

(d) Medium A is optically rarer and medium B is optically denser because when a light ray goes from optically rarer media to optically denser media then it bends towards the normal here light is bending towards the normal as angle is decreasing
