Wave Speed Equation Practice

Front

What is the wave speed equation?

Back

The wave speed equation is given by the formula: v = f × λ, where v is the wave speed, f is the frequency, and λ (lambda) is the wavelength.

Front

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

Back

To calculate the speed of a wave, multiply the frequency (f) by the wavelength (λ): v = f × λ.

Front

What is frequency in the context of waves?

Back

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

Front

What is wavelength in the context of waves?

Back

Wavelength is the distance between successive crests (or troughs) of a wave, typically measured in meters.

Front

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

Back

The speed of the wave is 20 m/s, calculated using the formula v = f × λ (10 Hz × 2 m = 20 m/s).

Front

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

Back

If the frequency increases while the wavelength remains constant, the wave speed will increase.

Front

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

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa, when wave speed is constant.

Front

How do you find the wavelength if you know the wave speed and frequency?

Back

To find the wavelength, rearrange the wave speed equation: λ = v / f.

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 300 m/s and has a frequency of 150 Hz, what is its wavelength?

Back

The wavelength is 2 meters, calculated using λ = v / f (300 m/s / 150 Hz = 2 m).
