Question

Light travels from air into water with an index of refraction of 1.33 . The light ray will:

A.

go perpendicular to the normal

B.

bend away from the normal

C.

bend towards the normal

D.

go parallel to the normal

Correct option is C

The correct answer is:(C). bend towards the normal
Here's why:
  • Refraction: When light travels from one medium to another with a different density, its speed changes, causing it to bend. This bending is called refraction.

The light ray will bend towards the normal as it travels from air into water.

  • Denser Medium: Water is denser than air, meaning light travels slower in water.
  • Bending: When light enters a denser medium (like water from air), it bends towards the normal. The normal is an imaginary line perpendicular to the surface at the point where the light enters.
