The same progressive wave is represented by two graphs I and II. Graph I shows how the displacement `y` varies with the distance x along the wave at a given time. Graph II shows how y varies with time t at a given point on the wave. The ratio of measurements AB to CD, marked on the curves represents:

Options

A. wave number k
B. wave speed V
C. frequency n
D. angular frequency `omega`

Answer

b

Explanation

`(measure AB)/(measure CD)=(lambda)/(T)=(1//K)/(1//W)=V_(Omega)`
