Waves Review

Front

What is the Doppler Effect?

Back

The Doppler Effect is the apparent change in pitch of a sound due to the relative motion between the observer and the source of the sound.

Front

What is wavelength in the context of waves?

Back

Wavelength is the distance between two corresponding parts of a wave, such as crest to crest or trough to trough.

Front

What are the highest points of a transverse wave called?

Back

The highest points of a transverse wave are called crests.

Front

What is a medium in wave terminology?

Back

A medium is any material through which a wave travels.

Front

How can you identify the wave with the greatest frequency?

Back

The wave with the greatest frequency has the most number of crests or cycles in a given time period.

Front

What is frequency in relation to waves?

Back

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

Front

What is amplitude in wave terminology?

Back

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

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the particle displacement is parallel to the direction of wave propagation.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a transverse wave.

Front

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

Back

The pitch of the sound decreases as the source moves away from the observer, a phenomenon explained by the Doppler Effect.
