The amplitude and phase of a wave that is formed by the superposition of two harmonic travelling waves, $\displaystyle \mathrm{y}_1(x, \mathrm{t})=4 \sin (\mathrm{k} x-\omega \mathrm{t})$ and $\displaystyle \mathrm{y}_2(x, \mathrm{t})=2 \sin \left(\mathrm{k} x-\omega \mathrm{t}+\frac{2 \pi}{3}\right)$, are:
(Take the angular frequency of initial waves same as $\displaystyle \omega$ )
