When light travels from a more dense medium (like water) to a less dense medium (like air), it bends away from the normal.

Here's a breakdown:

* Normal: An imaginary line perpendicular to the surface where the light is entering or leaving.

* Angle of incidence: The angle between the incoming light ray and the normal.

* Angle of refraction: The angle between the refracted light ray (the light ray after bending) and the normal.

In this scenario:

* Angle of refraction is greater than the angle of incidence. This means the light ray bends further away from the normal.

Think of it this way:

Imagine a car driving on a smooth surface and then suddenly hitting loose sand. The car will veer off course, just like the light bends away from the normal when entering a less dense medium.

This bending of light is called refraction.
