Question

Please the answer the questions given below

The observation made by Swarali while doing the experiment are given below.
Based on these write answers to the following questions:

Swarali found that the light ray travelling 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) also went on increasing. However after certain
value of the angle of incidence the light ray is seen to return back into the denser
medium.


1) Name a certain value of i .What is the value of r at that time ?
2) Name the process of returning of light in the denser medium .Explain the process ​
