Question

from the below mentioned options choose the situation where total internal reflection may takes place
A) when light travels from denser medium to rarer medium
B) when light travels from rarer medium to denser medium
C) when light is travelling in rarer medium
D) A&B​

Answer 1

Answer:

⚡OPTION A IS YOUR ANSWER ⚡

Toal internal reflection happens at the bondary of two media of different refractive index. hence option c is wrong.

The condition of total internal reflection requires light to bend away from normal till it is 90⁰ from normal. In case of option B light rays bend towards normal. Hence option b is wrong.
