The equation of a progressive wave is
`y = A sin (omega t - (2pi x)/(lamda))`. In terms of frequency and velocity of the wave, this equation is written as:

Options

A. `y = A sin 2pi n (t - (v)/(x))`
B. `y = A sin 2pi n (t - (x)/(v))`
C. `y = A sin 2pi (n t- (x)/(v))`
D. `y = 2A sin pi (nt = (x)/(v))`

Answer

B

Explanation

`y = A sin (w t - (2pi x)/(lamda)) " but " omega = 2pi n and lamda = (v)/(n)`
`:. y = A sin [2pi n t - (2pi xn)/(v)] = A sin 2pi n [t' - (x)/(v)]`
