Question

light changes its path when it passes through which thing? please answer fast​

Answer 1

Explanation:

Light waves change speed when they pass across the boundary between two substances with a different density , such as air and glass. This causes them to change direction, an effect called refraction .

Answer 2

Answer:

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.
