Wave Speed Equation Practice

Front

What is the wave speed equation?

Back

Wave speed (v) = Frequency (f) × Wavelength (λ)

Front

Define wavelength.

Back

Wavelength is the distance between successive crests (or troughs) of a wave.

Front

What is frequency in the context of waves?

Back

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

Front

How do you calculate the speed of a wave if you know its frequency and wavelength?

Back

Use the wave speed equation: v = f × λ.

Front

If a wave has a frequency of 10 Hz and a wavelength of 2 m, what is its speed?

Back

20 m/s (v = 10 Hz × 2 m).

Front

What is the unit of wave speed?

Back

The unit of wave speed is meters per second (m/s).

Front

If a wave travels at 30 m/s and has a wavelength of 3 m, what is its frequency?

Back

10 Hz (f = v / λ = 30 m/s / 3 m).

Front

What happens to the speed of a wave if the frequency increases while the wavelength remains constant?

Back

The speed of the wave increases.

Front

What is the relationship between frequency and wavelength in a wave?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases if speed is constant.

Front

If a wave has a speed of 15 m/s and a frequency of 5 Hz, what is its wavelength?

Back

3 m (λ = v / f = 15 m/s / 5 Hz).
