Frequency and wavelength are related to each other through the velocity of propagation and this relation is inversely proportional. A longer wavelength wave will need to move faster to keep at the same frequency. An audible sound wave possesses a frequency range of 20 to 20 kHz.
The Relationship between Wave Frequency Period Wavelength and Velocity Since wave frequency is the number of waves per second and the period is essentially the number of seconds per wave the relationship between frequency and period is f 1 T 131.
Assuming a sinusoidal wave moving at a fixed wave speed wavelength is inversely proportional to frequency of the wave. That is the speed of a wave is equal to its frequency multiplied by the wavelength. A more mathematically useful way to write 2 Hz is 2 s 1. In this screencast Andrew Burrows walks you through the relationship between wavelength and frequency in electromagnetic radiation.
