A transverse harmonic wave on a string i...

A transverse harmonic wave on a string is described by
` y (x , t) = 3 . 0 sin ( 36 t + 0 . 0 18 x + (pi)/(4) ) `
where x and y are cm and t in s. The positive direction of x is from left to right .
Is this a travelling wave or a stationary wave ?
. If it is travelling, what are the speed and direction of its propagation ?

Text Solution

Verified by Experts

The correct Answer is:
A travelling wave . It travels from right to left with a speed of ` 20 m*s^(-1) ` ;
