• It passes through the surface.

• It gets absorbed by the surface.

• It bounces off the surface.

• It disappears.

When light moves from air into water, it bends. What is this bending of light called?

• Reflection

• Refraction

• Diffraction

• Absorption

If you look at a pencil in a glass of water, it looks bent at the surface of the water. What causes this?

• Reflection

• Refraction

• The pencil is actually bent.

• The water is moving.

Which of the following surfaces would reflect light the best?

• A rough and dark surface

• A smooth and shiny surface

When light waves enter a new medium and slow down, what happens to their wavelength?

• It increases.

• It decreases.

• It stays the same.

• It disappears.

Why can we see our reflection in a calm lake?

• Because of the refraction of light in water.

• Because of the diffusion of light in water.

• Because of the reflection of light on the water's surface.

• Because of the absorption of light by the water.

What happens to the speed of light when it passes from a denser medium to a less dense medium?

• It increases.

• It decreases.

• It stays the same.

• It stops.

How does the color of a surface affect its ability to reflect light?

• Darker colors reflect more light.

• Lighter colors absorb more light.

• Lighter colors reflect more light.

• Color has no effect on light reflection.
