What is occurring to the light when it comes in contact with the water?The light is scattering.

• The light is scattering.

• The light is reflected.

• The water is absorbing the light.

• The light passes through the water with no effect.

Describe what happens when light strikes a dark, non-shiny surface.

• Light is reflected outward.

• Light is refracted as it passes through.

• Light is absorbed by the surface.

• Light is bent around the object.
