Question

If you increase the frequency of a sound wave four times, what will happen to its speed?

Answer 1

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:

$F = \frac{V}{\lambda}$

Where:

• F is the frequency of a sound wave.

• V is the velocity of a sound wave.

• $\lambda$ 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;

$4F = \frac{V}{\lambda}\\\\V=4F\lambda$

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