Waves, Light, and Sound Practice Test RECOVERY

Front

What does the Law of Reflection state?

Back

The angle of incidence is equal to the angle of reflection.

Front

What does compression in a wave represent?

Back

Compression is the area in a longitudinal wave where particles are close together.

Front

Can sound waves travel through empty space?

Back

No, sound waves cannot travel through empty space.

Front

What determines the pitch of a sound?

Back

The pitch of a sound depends on the frequency of the sound waves.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What is wavelength in a wave?

Back

Wavelength is the distance between successive crests or troughs in a wave.

Front

What is the difference between compression and rarefaction in sound waves?

Back

Compression is where particles are close together, while rarefaction is where particles are spread apart.

Front

What type of wave is sound?

Back

Sound is a longitudinal wave.

Front

What is the relationship between frequency and wavelength?

Back

Higher frequency waves have shorter wavelengths.

Front

What happens to sound as it travels through different mediums?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases.
