Wave Motion and Energy Transfer

Front

What is a natural vacuum which sound cannot travel through?

Back

Outer space

Front

What happens to the pitch of a sound as the source moves away from the observer?

Back

The pitch decreases.

Front

Which part of a longitudinal wave is where particles are packed closely together?

Back

Compression

Front

Which property of these waves differs? (Frequency, Wavelength, Amplitude, Pitch)

Back

Amplitude

Front

What type of wave is this? (Longitudinal, Transverse)

Back

Transverse

Front

What is the definition of wave motion?

Back

Wave motion is the transfer of energy through a medium without the permanent displacement of the medium itself.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the direction of wave propagation; in transverse waves, particles move perpendicular to the direction of wave propagation.

Front

What is frequency in the context of wave motion?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What is amplitude in wave motion?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.
