Waves Review

Front

What is amplitude in a wave?

Back

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

Front

What is the formula for wave velocity?

Back

Wave velocity = frequency x wavelength.

Front

How do you calculate the frequency of a wave if the velocity is 0.50 m/s and the wavelength is 0.1 m?

Back

Frequency = velocity / wavelength = 0.50 m/s / 0.1 m = 5 Hz.

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.

Front

Which wave has the greatest frequency in a diagram?

Back

The wave with the shortest wavelength has the greatest frequency.

Front

What is wavelength in a wave?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the unit of frequency?

Back

The unit of frequency is Hertz (Hz), which represents cycles per second.

Front

What happens to the amplitude of a wave as energy increases?

Back

As energy increases, the amplitude of the wave also increases.

Front

What is the difference between transverse and longitudinal waves?

Back

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