A certain sound wave has a wavelength of 2 m and a frequency of 170 hertz. calculate the velocity of this wave.

The velocity of the wave with the given wavelength and frequency is 340m/s.

Given the data in the question;

Velocity;

To determine the velocity of the wave, we use the expression for the relations between wavelength, frequency and speed.

Where is wavelength, f is frequency and v is speed.

We substitute our given values into the equation

Therefore, the velocity of the wave with the given wavelength and frequency is 340m/s.

340m/s

Explanation:

Given parameters:

Wavelength  = 2m

Frequency   = 170Hz

Unknown:

Velocity of the wave  = ?

Solution:

The velocity of the wave is the product of frequency and wavelength of the wave;

          V  = F λ

V is the velocity

 F is the frequency

λ is the wavelength

  Insert the parameters and solve;

          V = 2  x 170 = 340m/s

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
