The speed will increase four (4) times when the frequency of sound wave is increased four (4) times.

How to calculate the frequency of a wave.

Mathematically, the frequency of a sound wave is given by this formula:

[tex]F = \frac{V}{\lambda}[/tex]

Where:

  • F is the frequency of a sound wave.
  • V is the velocity of a sound wave.
  • [tex]\lambda[/tex] is the wavelength of a sound wave.

Note: The frequency of the sound wave is increased four (4) times.

  • F = 4F

Substituting the given parameters into the formula, we have;

[tex]4F = \frac{V}{\lambda}\\\\V=4F\lambda[/tex]

Therefore, the speed will increase four (4) times when the frequency of sound wave is increased four (4) times.
