Question

36. When the angle of incident is greater than the critical angle what is the light of
reflected?​

Answer 1

please mark me as brainliest

Explanation:

When the angle of incidence of a ray is greater than the critical angle, the reflected ray is in the same medium, i.e. the light is totally reflected in the same medium. This is known as total internal reflection. The angle of incidence of a ray for which the angle of refraction is 90∘ is called critical angle.

Answer 2

Answer:

this is called total internal reflection

Explanation:

the angle of refraction is 90 degree is called critical angle
