A plane prohressive wave is given by y=2...

A plane prohressive wave is given by `y=2 cos 6.284 (330t-X)`. What is period of the wave?

A

`1/330 s`

B

`2 pi xx 330 s`

C

`(2 pi xx330)^(-1) s`

D

`6.284/330 s`

Text Solution

Verified by Experts

The correct Answer is:
A
We have the progressive wave given by
`y=2 cos 6.284 (330t-x)`
`=2 cos 2 pi (330 t-x)`
`=2 cos (2pi xx330 t-2 pi x)`
`omega=2pi xx330`,
and time period, `T=(2pi)/omega =1/330 s`.
