Let f be the frequency, v wav the speed, and T the period of a sinusoidal traveling wave. The correct relationship is:

a)f=1/T

b)f=vwav + T

c)f=vwavT

d)f=vwav/T

e)f=T/vwav

My thoughts:

I think the answer is D.Since frequency is equal to T=1/f so f=1/T. Vwav is connected to f by the equation v=lambda* frequency. so together you

so I figured that it would come out to be f=vwav/T

For a transverse wave on a string the strong displacement is described as y(x,t)=f(x-at), where f is a given function and a is a positive constant. Which of the following does not necessarily follow this statement?

a)the shape of the string at time t=o is given by f(x)

b) the shape of the waveform does not change as it moves along a string

c) the waveform moves in the positive x direction

d) the speed of the waveform is a

e) the speed of the waveform is x/t

thoughts:

I think the statement that does not necessarily apply is d. The a in the equation is not refering to the wave speed but to the angular frequency or w based on the equation.

y=Ysin(kx-wt)

Thank you for your help.

How can you have both f = 1/T and f = Vwav/T ? The second equation is dimensionally inconsistent.

Your second answer is also wrong. The question has nothing to do with angular velocity.
