Write the definition of the angular frequency of a wave and its $SI$ unit.
(N/A) The angular frequency $(\omega)$ of a wave is defined as the rate of change of the phase of the wave with respect to time.
It represents the number of radians the wave oscillates per unit of time.
Mathematically, it is given by $\omega = 2\pi f$, where $f$ is the frequency of the wave.
The $SI$ unit of angular frequency is radians per second $(rad/s)$.
