उत्तर
Necessary conditions for total internal reflection to occur are:
(i) The incident ray on the interface should travel in optically denser medium.
(ii) The angle of incidence should be greater than the critical angle for the given pair of optical media.

Which colour of light has a higher critical angle? Red light or green light.
A light ray does not bend at the boundary in passing from one medium to the other medium if the angle of incident is ______.
Swarali has got the following observations while doing an experiment. Answer her questions with the help of observations.
Swarali observed that the light bent away from the normal, while travelling from dense medium to rarer medium. When Swarali increased the values of angle of incidence (i), the values of angle of refraction (r) went on increasing. But at a certain angle of incidence, the light rays returned into the dense medium.
So, Swarali has some questions. Answer them –
a) Name this certain value of ‘i ’. What is the value of ‘r’ at that time ?
b) Name this process of returning of light in dense medium. Explain the process.
Define critical angle for a given medium.
How does a ray of light bend when it travels from rarer to denser medium
