The displacement y of a wave travelling in the x- direaction is given by y = 10^(-4) sin (600t -2x + pi//3) Where x is expreseend in metres and t is seconds. What is the speed of the wave motion (in ms^(-1)) ?

The displacement y of a wave travelling in the x- direaction is given

1.	The displacement y of a wave travelling in the x- direaction is given by y = 10^(-4) sin (600t -2x + pi//3) Where x is expreseend in metres and t is seconds. What is the speed of the wave motion (in ms^(-1)) ?
Answer» Solution :`y = 10^(-4) sin(600t - 2x + pi/3) and y = a sin (omegat -kx +pi/3)` `:.omega = 600 RED s^(-1),K = 2 red^(-1)m` `v = omega/k= 600/2 = 300ms^(-1)`
