Define frequency of simple harmonic motion.

Explanation

(i) The number of oscillations produced by the particle per second is called frequency.
(ii) It is denoted by f . SI unit for frequency is `s^(-1)` or hertz (In symbol , Hz ).
(iii) Angular frequency is related to time period by `f=(1)/(T)`
(iv) The number of cycles (or revolutions ) per second is called angular frequency.
(v) Angular frequency and frequency are related by `omega=2pif`
(vi) SI unit for angular frequency is rad `s^(-1)`.
