Properties of Waves

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

True or False: Wavelength is the distance from rest to the highest or lowest point.

Back

False

Front

What is amplitude in the context of waves?

Back

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

Front

True or False: Amplitude and wavelength are the same.

Back

False

Front

What does the crest of a wave represent?

Back

The crest is the highest point of a wave.

Front

If five waves pass a point in 37 seconds, how do you calculate frequency?

Back

Frequency (f) is calculated as the number of waves (n) divided by the time (t) in seconds: f = n/t. In this case, f = 5/37 = 0.135 Hz.

Front

What is the formula for calculating wave speed?

Back

Wave speed (v) is calculated using the formula v = frequency (f) × wavelength (λ).

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is a wave's trough?

Back

The trough is the lowest point of a wave.

Front

What is the unit of frequency?

Back

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