(2) The observation made by Swarali while doing the experiment are given below.
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 went
on increasing. However, after certain value of the angle of incidence, the light ray is seen to return
back into the denser medium.
Questions :
(i) What is the specific value of Zi called?
(ii) What is the process of reflection of incident ray into denser medium called?
(iii) Draw the diagrams of three observations made by Swarali. ​
