Physics - SHM Question with Solution | TestHub

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