Refraction of Light

Refraction of light

The illusions occur as a result of the change in the direction of movement of light when light travels through two mediums of different densities

What happen when the incident ray moves from a more dense medium to a less dense medium

The light ray is refracted away from the normal

The light refracted towards the normal

The incident ray moves from a less dense medium to a more dense medium

The light ray is not refracted

The incident ray is parallel to the normal and moves from a less dense medium to a more dense medium

The incident ray is parallel to the normal and moves from a more dense medium (water) to a less dense medium (air)

The light is not refracted
