Light

What happens when light hits a shiny or smooth surface?

• It disappears

• It is refracted

• It is absorbed

• It is reflected

What is the angle of reflection equal to?

• the angle of refraction

• the angle of incidence

• the angle of absorption

• the angle of light

What might explain why light travels in a straight line?

• If there is nothing to interfere with light waves, they should travel in a straight line.

• Light waves will always travel in a straight line, even if they come into contact with another object.

• Light waves don't travel in a straight line.

• Light waves travel in a straight line because sound waves travel in a straight line.

What is it called when light bends as it moves from one substance to another?

• absorption

• reflection

• refraction

• incidence

Why doesn't the surface of a wooden boat reflect light as the surface of water does?

• Because the boat's surface is rough and absorbs more light.

• Because the surface of the boat is red, not blue.

• Because the boat is not a natural object like water is.

• Because the boat is on top of the waters surface.

What is the angle of incidence?

• The angle at which light bends in water.

• The angle at which light hits a surface.

• The angle at which light is absorbed by an object.

• The angle at which light bounces off an surface.

When you look into a mirror, what is happening to the light?

• It is increasing in wavelengths.

• It is being refracted.

• It is being absorbed.

• It is being reflected.
