Question

what is the refractive index of the prism when the critical angle is 45°​

Answer 1

in the case of critical angle

refractive index of prism =1/sinθ

refractive index of prism =1/sin45

refractive index of prism =√2

hope this helps you

please mark the answer as brainlest please

Answer 2

The refractive index of prism when the critical angle is 45° is 1.414.

It can be determined as follows :

Solution:

•Critical angle and refractive index can be related by the formula,

n=1/sinc

where n=refractive index and c=critical angle.

•Substituting value of c as 45°,

we get, n=1/sin45°

which implies,. n=1/0.7071

Then,. n=1.414.

•Therfore,the refractive index of prism is 1.414.
