What is the best beat frequency?

Speed and frequency are two different things . Speed refers to the distance covered in a set amount of time.

The speed of a wave is unaffected by changes in the frequency .

Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency . This equation can be used to calculate wave speed when wavelength and frequency are known.
