Question

If light enters glass from air, then its velocity will -

a) Increase

b) Decrease

c) Remain same

d) Become zero

Correct answer please...

​

Answer 1

Explanation:

The energy of the light is unchanged as it passes from one media to another. Whenvisible light in air enters a medium such as glass, the velocity of light decreases to 75% of its velocity in air and in other materials thedecrease can be even more substantial. ... Forair, the velocity is 99.97% of the speed in vacuum.

Answer 2

Answer:

Hello mate ✌️

Explanation:

options b is correct answer ❣️.

Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, too. The wavelength decreases as the light enters the medium and the light wave changes direction.

hope it will be helpful to you ✌️✌️
