The speed will increase four (4) times when the frequency of sound wave is increased four (4) times.
<h3>How to calculate the frequency of a wave.</h3>Mathematically, the frequency of a sound wave is given by this formula:
<u>Where:</u>
- F is the frequency of a sound wave.
- V is the velocity of a sound wave.
is the wavelength of a sound wave.
<u>Note:</u> The frequency of the sound wave is increased four (4) times.
- F = 4F
Substituting the given parameters into the formula, we have;
Therefore, the speed will increase four (4) times when the frequency of sound wave is increased four (4) times.
