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.

A monochromatic beam of light passes from a denser medium into a rarer medium. As a result

The ray of light travelling from an optically denser medium to optically rarer medium bends

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

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 refreaction is

Explain reflection of longitudinal wave travelling from denser to rarer medium.
