Frequency is a measurement of how often a recurring event such as a wave occurs in a measured amount of time. One completion of the repeating pattern is called a cycle. Only moving waves which vary their positions with respect to time possess frequency. Frequency is one way to define how fast a wave moves.
How does the frequency of a wave vary with the wave length? Wavelength(Î») is equal to the speed of the wave(v) divided by the frequency(f). Find the frequency of a sound wave moving in air at room temperature with the wavelength of 0.667m? At 20 degrees Celsius or 68 degrees Fahrenheit the speed of sound c = 343 m/s.
