Phasors are useful for adding waves that are out of phase. For example, assume you have two sources, 1 and 2, that emit sound waves of the same frequency \(f\). At your detector, the waves from source 1 have an amplitude of \(1.00 \times 10^{-8} \mathrm{~m}\), and those from source 2 have an amplitude of \(0.600 \times 10^{-8} \mathrm{~m}\) and a phase of \(+\pi / 3\) relative to the phase of the source 1 waves. If the phase of the waves from source 1 is arbitrarily assigned to be \(\phi_{1}=0\), what are the amplitude and phase of the combined waves?
