Next

426 Hertz

Explanation:

We are given;

The velocity of the wave as 341 m/s Wavelength as 0.8 meters

We are required to calculate the frequency of the wave.

We need to know that the velocity of a wave is the product of frequency and wavelength. That is;

Velocity = frequency * wavelength

Rearranging the formula;

Frequency = Velocity : wavelength

Therefore;

Frequency = 341 m/s : 0.8 m

= 426.25 Hertz

= 426 Hertz

Thus, the frequency of the wave is 426 Hertz
