A ray of light in travellingfrom air to water when is the angle of incidence in air if angle r 41 degree in water? Take refractiveindex of water 1.32​

Answer»

Answer:

Explanation:

In this case, the angle of refraction (r) is greater than the angle of INCIDENCE (i). Also, WATER is an optically denser than air, so when a beam of light enters into air, it BENDS AWAY from the normal. When a ray of light goes from a rarer medium to a denser medium, its speed decreases or it slows down.
