The displacement y of a wave travelling ...

The displacement y of a wave travelling in the x direction is given by `y=(2 xx 10^(-3)) sin(300t - 2x + pi/4)`, where x and y are measured in metres and t in second. The speed of the wave is

A

150 `ms^(-1)`

B

300 `ms^(-1)`

C

450 `ms^(-1)`

D

600 `ms^(-1)`

Text Solution

Verified by Experts

From standard equation of wave, Y = a sin `(omegat - kx + phi)`
`omega` 300 , k = 2
Speed of wave, `V = (omega)/(k) = (300)/(2) = 150 ms^(-1)`
