Plane progressive wave y=Asin(omegat-kx)...

Plane progressive wave y=`Asin(omegat-kx)` travels in positive X-direction with a speed

A

`omega`

B

`(omega)/(k)`

C

`(k)/(x)`

D

`v`

Text Solution

Verified by Experts

The correct Answer is:

B

Plane progressive wave has the equations `y=Asin(omegat-kx)`
`Y=Asin(kx-omegat)` both the equations represent a wave travelling in positive X-direction with a speed `v=omega//k`.
