Question

what is meant by total internal reflection​

Answer 1

Answer

When light travels from a denser medium to a rarer medium and is incident at an angle more than the critical angle for that medium, it is completely returned inwardly in the denser medium. This complete inward return of light is called total (complete) internal (inward) reflection (return).

Explanation:

In such a case, a light ray will bend away from the normal. The angle of refraction is larger than the angle of incidence. A small part of the incident ray is reflected inside the water.
