Unit 3 Wave & Electromagnetic Radiation Test

A student places a cork upright in a wave tank filled with water. The image shows how a wave ripples across the tank. 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 can move through empty spaces.

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

• Mechanical waves transfer energy but not matter.

• Mechanical waves do not carry energy.

A beam of white light shines on a filter in an arrangement, as shown. Which properties of light are demonstrated when the white light strikes the filter and the blue light moves toward the red object?

• absorption and refraction

• absorption and transmission

• refraction and reflection

• transmission and refraction

Based on the experiment, what conclusion can be made about light waves and sound waves?

• Light waves move through glass, but sound waves do not.

• Light waves move in a straight path, but sound waves do not.

• Sound waves need a medium such as air to transmit, but light waves do not.

• Sound waves need energy such as electricity to transmit, but light waves do not.

A sound-proof window has two panes of glass with a vacuum in between. 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.

• change in media

• change in altitude

• increase in pressure

• increase in temperature

Frank shined a beam of light at the surface of a mirror. A piece of paper above the mirror was lit up. What caused the light to shine on the paper above the mirror?

• The light was refracted.

• The light was reflected.

• The light was amplified.

• The light was diffracted.
