If the wavelength of a wave is 4 m, and the wave velocity is 8 m/s, then the frequency is _______?

The frequency is 2 Hz.

To calculate frequency, we use the formula:

frequency = velocity / wavelength

Plugging in the given values:

frequency = 8 m/s / 4 m

frequency = 2 Hz

The formula to calculate the frequency of a wave is:

Frequency = Wave velocity / Wavelength

Given that the wavelength is 4 m and the wave velocity is 8 m/s, we can substitute these values into the formula:

Frequency = 8 m/s / 4 m

Simplifying the expression:

Frequency = 2 Hz

Therefore, the frequency of the wave is 2 Hz.
