In order to reduce losses in an optical fibre, the angle of incidence of the lig

Question

In order to reduce losses in an optical fibre, the angle of incidence of the light to the wall of the core should be a. less then the critical angle for total internal reflection b. less then the critical angle for total internal reflection In order to reduce losses in an optical fibre, the angle of incidence of the light to the wall of the core should be a. less then the critical angle for total internal reflection b. less then the critical angle for total internal reflection In order to reduce losses in an optical fibre, the angle of incidence of the light to the wall of the core should be a. less then the critical angle for total internal reflection b. less then the critical angle for total internal reflection

Explanation / Answer

In order to reduce losses in an optical fiber the angle of incidence of the light to the wall of core should be more the the critical angle for total internal reflection.

Because of that light will stay within optical fiber and will not go out .

Answer:- more than the critical angle for the total internal reflection .
