Question: Consider two wave functions that differ only by a phase shift, y_{1}\left( {x,t} \right) = A\ \text{cos}\left( {kx - \omega t} \right) and y_{2}\left( {x,t} \right) = A\ \text{cos}\left( {kx - \omega t + \phi} \right). Use the trigonometric identities \text{cos}\ u + \text{cos}\ v = 2\ \text{cos}\left( \frac{u - v}{2} \right)\text{cos}\left( \frac{u + v}{2} \right) and \text{cos}\left( {\text{−}\theta} \right) = \text{cos}(\theta) to find a wave equation for the wave resulting from the superposition of the two waves. Does the resulting wave function come as a surprise to you?
