Question

If the speed of a wave is 380 m/s and its frequency is 1900 Hz, then the wavelength of the wave will be

Answer 1

Given:

• Speed of wave, v = 380 m/s

• Frequency of wave, f = 1900 Hz

To be calculated:

Calculate the wavelength of the wave.

Formula used:

Velocity = frequency × wavelength

Solution:

We know that the formula for calculating the wavelength of a sound wave ,

velocity = frequency × wavelength

Putting the values of velocity and frequency in the above formula, we get

➱ 380 = 1900 × wavelength

➱ wavelength = 380/1900

➱ wavelength = 38/190

➱ wavelength = 2/10

➱ wavelength = 0.2

Thus, the wavelength of sound wave is 0.2 m.
