A wave travelling in the positive x-direction having displacement along y-direaction as ,
1m wavelength `2pi`m and frequency of `1/pi`

A

`y=sin(x-2t)`

B

`y=sin(2pi x - 2pi t)`

C

`y=sin(10pi x-20 pi t)`

D

`y=sin(2pi x+2pi t)`

Text Solution

Verified by Experts

The correct Answer is:
A
`y=a sin (omegat-kx)`
`" "`OR
`y=a sin(kx-omegat)`
`therefore y=sin[x-2t] " "`...(1)
`k=(2pi)/(lambda)=(2pi)/(2pi)`
`omega=2pi.v=2pi.(1)/(pi)=2`
`a=1m`
