A wave travelling in the `+ve` x-direction having displacement along y-direction as 1`m`, wavelength `2pi` m and frequency of `1//pi` Hz is represented by

A

`y= sin (x-2t)`

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
Given, `a=1 m`
As `y=a sin (kx-omega t)=sin ((2pi)/(2pi)x-2pi xx1/2 t)`
`=sin (x-2t)`
