The obeervation made by Swarali while doing the experiment are
ven below, Baned on thone write answers to the quention
Swarali found that the light ray travelling from the denser medium
to rarer medium goon away from the normal. If the angle of
eidence in rained by Swarali, the angle of refraction (r) went
n inereasing. However after certain value of the angle of incidence
the light ray is soen to return back into the denser medium.
Questions
.
1..
What ia the specific value of Li called ?
2..What is the process of reflection of incident ray into denser
medium called ?
3..Draw the diagrams of three observations made by Swarali.

- i think Li= 90°
- the light ray go from denser to rarer medium it bends towards the normal.
- 1 )is ray daigram
- 2) critical angle.
- 3)total internal reflection

The answers of the given questions are following -
When the refraction angle reaches to the 90 degree absolute value, both of the angle of refraction and angle of incidence are getting increased.
The value is also known as absolute value.
The process can be called as the total internal reflection.
When the light reaches to the point where the angle of refraction meets to the absolute value, it reflects out.
The process can be visible in case of rainbow formation.
