Which of the following equations represents a wave travelling along y-axis?

A)  \[y=A\,\sin \,(Kx-\omega t)\]

B)  \[x=A\,\sin \,(Ky-\omega t)\]

C)  \[y=A\,\sin \,Ky\,\cos \,\omega t\]

D)  \[y=A\,\cos \,Ky\,sin\,\omega t\]

Correct Answer: B

Solution :

The equation given is \[x=\sin \,(ky-\omega t)\]represents a wave travelling along y-axis, where A is the amplitude.
