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
What is the process of reflection of incident ray into a denser medium called ?

When light ray travels from denser medium to rarer, then it

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

When wavefronts pass form denser medium to rarer medium the width of the wavefront

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.
