In the equation $y = A \sin (kx - \omega t + \phi_0)$, the term phase is defined as

In the equation $y = A \sin (kx - \omega t + \phi_0)$, the term phase is defined as
  1. $\phi_0$
  2. $\phi_0 - \omega t$
  3. $kx + \phi_0$
  4. $kx - \omega t - \phi_0$

Solution

Here, the phase is $(kx - \omega t + \phi_0)$.
