Physics - Sound Wave Question with Solution | TestHub

Five sinusoidal waves have the same frequency $500\mathrm{Hz}$ but their amplitudes are in the ratio $2:\frac{1}{2}:\frac{1}{2}:1:1$ and their phase angles $0,\frac{\pi }{6},\frac{\pi }{3},\frac{\pi }{2}$ and $\pi$ respectively. The phase angle of resultant wave obtained by the superposition of these five waves is
