Question

The diagram below shows an instantaneous position of a string as a transverse progressive wave travels along it from left to right

Which one of the following correctly shows the direction of the velocity of the points 1, 2 and 3 on the string

Infinity Learn · Accepted Answer

Particle velocity (vp)=$$− v×Slope of the graph at that pointAt point $$1$$ : Slope of the curve is positive, hence particle velocity is negative or downward $$($$↓$$)At$$ point $$2$$ : Slope negative, hence particle velocity is positive or upwards $$($$↑$$)At$$ point $$3$$ : Again slope of the curve is positive, hence particle velocity is negative or downward $$($$↓$$)
