Q3 W9 Wednesday

What happens when light hits a smooth, shiny surface like a mirror?

• It passes through the mirror.

• It gets absorbed by the mirror.

• It bounces off the mirror.

• It makes the mirror warmer.

When light bends as it passes from air into water, this is called:

• Reflection

• Refraction

• Diffraction

• Absorption

What is the term used to describe the bouncing back of light from a surface?

• Refraction

• Reflection

• Absorption

• Transmission

If you increase the amplitude of a light wave, what happens to the light?

• It gets dimmer.

• It changes color.

• It gets brighter.

• It moves slower.

Which of the following materials will light not pass through?

• Glass

• Water

• Wood

• Clear plastic

What is it called when light changes direction because it moves from one material into another?

• Reflection

• Refraction

• Diffraction

• Polarization

What does the amplitude of a light wave affect?

• The speed of the light

• The brightness of the light

• The color of the light

• The direction of the light

When light moves from water to air, it bends away from the normal. This is an example of:

• Reflection

• Refraction

• Diffraction

• Absorption
