Question

How are the wavelength and frequency of a sound wave related to its speed?

Answer

The speed (v), wavelength (\lambda), and frequency (\nu) of a sound wave are related by the formula:

Speed = Wavelength × Frequency

v = \lambda \times \nu

This means that for a constant speed in a given medium, as the frequency increases, the wavelength decreases, and vice versa.
