16.5 Exercise 13

Two sinusoidal waves, which are identical except for a phase shift, travel along in the same direction. The wave equation of the resultant wave is $y_{R} \left(x , t\right) = 0.70 \text{m} \text{sin} \left(\right. 3.00 \text{m}^{−1} x - 6.28 \text{s}^{−1} t +$
$\pi / 16 \text{rad} \left.\right) .$ What are the angular frequency, wave number, amplitude, and phase shift of the individual waves?
