Q. A standing wave is formed by the superposition of two waves travelling in opposite directions. The transverse displacement is given by $y(x, t)=0.5 \sin \left(\frac{5 \pi}{4} x\right) \cos (200 \pi t)$ What is the speed of the travelling wave moving in the positive $x$ direction?

Solution:

$V=\frac{\omega}{K}$
