Wave Properties and Traits Unit Test

The cork does not change its position within the wave; instead, it moves up and down in its original position. What can be concluded about mechanical waves from this activity?

• Mechanical waves carry the particles of mediums along with the waves.

• Mechanical waves can move through empty spaces.

• Mechanical waves transfer energy but not matter.

• Mechanical waves do not carry energy.

Which wave best demonstrates the wave behavior of absorption?

• wave J

• wave K

• wave L

• wave M

Why is sound unable to travel through the window while light can still shine through?

• Sound has a different frequency than light, so it cannot pass through the window.

• Sound has a different wavelength than light, so it cannot pass through the window.

• Light can travel through both the glass and the vacuum, but sound can travel only through the glass.

• Light can travel through both the glass and the vacuum, but sound can travel only through the vacuum.

What happens to a ray of white light when it passes through a prism?

• The ray of light is combined into a single color.

• The ray of light is completely absorbed by the prism.

• The ray of light is bent backward toward the source of light.

• The ray of light is bent in several pathways showing a rainbow.
