Waves Review

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What does the term 'crest' refer to in wave terminology?

Back

The crest is the highest point of a wave.

Front

What is the definition of wavelength?

Back

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

Front

What is the definition of trough in wave terminology?

Back

The trough is the lowest point of a wave.

Front

How is frequency defined in the context of waves?

Back

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

Front

What is the formula to calculate wave speed?

Back

Wave speed (c) is calculated using the formula: c = fλ, where f is frequency and λ is wavelength.

Front

If a wave has a frequency of 500 Hz and a wavelength of 2 m, what is its wave speed?

Back

Using the formula c = fλ, the wave speed is c = 500 Hz * 2 m = 1000 m/s.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the formula to calculate frequency if the wave speed and wavelength are known?

Back

Frequency (f) can be calculated using the formula: f = c/λ, where c is wave speed and λ is wavelength.

Front

If a sound wave has a wavelength of 0.25 m and a wave speed of 330 m/s, what is its frequency?

Back

Using the formula f = c/λ, the frequency is f = 330 m/s / 0.25 m = 1320 Hz.
