Question

# In a sine wave, position of different particles at time is shown in figure. The equation for this wave travelling along positive can be

## The correct answer is:

### As is clear from figure, at, displacement. Therefore, option (a)or (d)may be correct.

In case of (d);

.

And slope at and is positive, in figure. Therefore, particle velocity is in negative y-direction.
