Answer the following questions The observations made by swarali while doing the experiment are given below. Based on these write answers to the questions: Swarali found that the light ray trvelling from the denser medium to a rarer medium goes away from the normal. If the angle of incidence (i) is raised by Swarali, the angle of refraction (r) went on increasing . However after certain value of the angle of incidence. the light ray is seen to return back into the denser medium Draw the diagram of three observations made by swarali.

When a monochromatic ray of light travels from an optically denser medium to optically rarer medium then critical angle is the angle of incidence for which angle of refraction is

The angle of refraction is always greater than the angle of incidence for a ray of light travelling from optically denser medium to a rarer medium.

Answer the following questions If the refractive index of a rarer medium with respect to a denser medium is 0.5 what is the critical angle ?

State whether the following statements are True or False : When a light ray travels obliquely from an optically rarer medium to an optically denser medium, it bends away from the normal.

Choose the correct alternative and write it along with its allotted alphabet: If a ray of light passes from a denser medium to a rarer medium in a straight line, the angle of incidence must be

When a ray of monochromatic light enters from rarer medium to denser medium obliquely, the angle of incidence i and angle of refraction r is related as

When a ray of monochromatic light enters from rarer medium to denser medium obliquely, the angle of incidence I and angle of refraction r is related is
