A wave is given by the equation Y = `10^(-4)` sin (60t + 2x) where x and y are in metres and t in second, then wavelength of the wave is :

A

`pi` metre

B

`2pi` metre

C

`(3pi)/(2)` metre

D

`3pi` metre

Text Solution

Verified by Experts

The correct Answer is:
A
`y = 10^(-4)` sin (60t + 2x)
Here w = 60t and k =2
Now k = `(2pi)/(lambda)`
`rArr lambda = (2pi)/(2) = pi ` metre
Hence correct choice is (a).
