Question

state the relation betwwen the refractive index and the critical angle​

Answer 1

Answer:

Relation Between Critical Angle And Refractive Index. In Optics, The angle of incidence to which the angle of refraction is 900 is called critical angle. The ratio of velocities of a light ray in the air to the given medium is refractive index.

Answer 2

critical angle is formed when the angle of refraction is equals to 90 degree.at this point light cannot pass through the surface .if n is the refractive index then the relation between refractive index and Critical Angle is given by :-

$sin \: e_{c} = \frac{1}{n}$

here ec is the critical angle.

so it is clear that the relation between refractive index and critical angles is inverse .hence this is the required solution .

Here is your answer.
