<P> For cyclical processes , such as rotation , oscillations , or waves , frequency is defined as a number of cycles per unit time . In physics and engineering disciplines , such as optics , acoustics , and radio , frequency is usually denoted by a Latin letter f or by the Greek letter ν ( \ displaystyle \ nu ) or ν ( nu ) ( see e.g. Planck 's formula ) . </P>
