A progressive wave travelling along the positive $ x- $ direction is represented by $ y(x, \mathrm{t})=\mathrm{A} \sin (\mathrm{k} x-\omega \mathrm{t}+\phi) $. Its snapshot at $ \mathrm{t}=0 $ is given in the figure. For this wave, the phase $ \phi $ is:, $ \frac{\pi}{2} $, $ 0 $, $ \pi $, $ -\frac{\pi}{2} $
