v = fλ

Where:

* v is the wave speed (in meters per second, m/s)

* f is the frequency of the wave (in Hertz, Hz)

* λ is the wavelength of the wave (in meters, m)

Explanation:

* Frequency (f) represents the number of wave cycles that pass a fixed point in one second.

* Wavelength (λ) is the distance between two consecutive crests or troughs of the wave.

This equation tells us that the speed of a wave is directly proportional to its frequency and wavelength. In other words, a wave with a higher frequency or a longer wavelength will travel faster.

Important Note: This equation applies to all types of waves, including:

* Mechanical waves: These waves require a medium to travel through, such as sound waves in air or water waves.

* Electromagnetic waves: These waves do not require a medium and can travel through a vacuum, such as light waves and radio waves.
