Question

when light enters into water from air, what change is observed in its speed? one or two sentence​

Answer 1

Explanation:

refraction

• When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.

Answer 2

Explanation:

refraction is your answer

when light travels from air into water it slows down causing it to change direction direction slightly this change of direction is called its fraction when light enters a more then substance it bends more towards the normal line
