Suppose that the position y of a particle that travels along

Suppose that the position, y, of a particle that travels along the Y axis of a coordinate system is given by: y(t) = y_0 sin[(3 pi/5)t + C. What is the frequency of the wave motion?

Solution

Compare it with

Y(t)=ASin(Wt+C)

so angular frequency

W=3pi/5

since frequency

f=W/2pi =(3pi/5)/2pi

f=0.3 Hz
