Question
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 $\left( {{{5\pi } \over 4}x} \right)\,$ cos(200 $\pi $t).
What is the speed of the travelling wave moving in the positive x direction ?
(x and t are in meter and second, respectively.)
