Question

the light will escape through optic fiber if the angle of incidence with cladding becomes​

Answer 1

Answer:

Therefore, the fiber-optic critical angle = (90 degrees - physics critical angle). In an optical fiber, the light travels through the core (m1, high index of refraction) by constantly reflecting from the cladding (m2, lower index of refraction) because the angle of the light is always greater than the critical angle.

Answer 2

Answer:

less than critical angle

Explanation:

It's reason is that when angle of incidence is greater than crtical angle ,light will totally reflected so according to this if angle of incidence is less than critical angle light will escape..
