The equation of a simple harmonic progressive wave having amplitude 5 mm, period 2 second and wavelength 2m and travelling along the positive direction of the x-axis is given by

Options

A. `y = 5 sin 2pi ((t)/(2) - (x)/(2))`
B. `y = 5 xx 10^(-3) sin 2pi (2t -(x)/(2))`
C. `y = 5 xx 10^(-3) sin 2pi ((t)/(2) - (x)/(2))`
D. `y = 5 xx 10^(-3) sin pi (2t - x)`

Answer

C

Explanation

The equations to be used is
`y = A sin 2pi [(t)/(T) - (x)/(lamda)] = 5 xx 10^(-3) sin 2pi [(t)/(2) - (x)/(2)]`
