Question

A wave travelling in the +ve x-direction having displacement along y-direction as 1m, wavelength 2π m and frequency of Hz is represented by :

Options

A.y = sin (2πx + 2πt)
B.y = sin (x - 2t)
C.y = sin (2πx - 2πt)
D.y = sin (10πx - 20πt)

Solution

and
So equation of wave y = sin(kx - ωt) = sin (x - 2t).
