For periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is. f = 1 T. 15.1. The SI unit for frequency is the hertz (Hz) and is defined as one cycle per second: 1Hz = 1cycle s or 1Hz = 1 s = 1s−1. A cycle is one complete oscillation. The relationship between the speed of sound, its frequency, and wavelength is the same as for all waves: v = fλ, v = f λ, 14.1. where v is the speed of sound (in units of m/s), f is its frequency (in units of hertz), and λ λ is its wavelength (in units of meters). Recall that wavelength is defined as the distance between adjacent identical ...
