Question

FIGURE Q16.8 is a snapshot graph of a sinusoidal wave at t = 1.0 s. What is the phase constant of this wave?

Short answer

The phase constant of the wave is 90 degrees.

Step-by-step solution

Step 1. Write the given information.

The snapshot of the sinusoidal wave at time t=1.0s

The speed of the wave is v= 1m/s

Step 2. To determine the phase constant of the wave

The phase constant of the wave describes the initial condition of the wave.

In the screenshot graph, it can be observed that the phase constant is $\frac{\pi }{2}$
