Frequency c wavelength

In physics, the term frequency refers to the number of waves that pass a fixed point in unit time . It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave . It is measured in the direction of the wave.

The time it takes to complete a cycle is the period. Frequency is the inverse of this, the number of cycles in a second. The distance sound travels during one period is the wavelength.
