Given that` y = A sin [((2 pi )/(lambda)(ct - x))]` where` y` and `x` are measured in metres ,Which of the following statements is true ?

A

The unit of `lambda^(-1)` is same as that of `(2pi)/(lambda)`

B

The unit of `lambda` is same as that of x but not of A

C

The unit of c is same as that of `(2pi)/(lambda)`

D

The unit of (ct - x) is same as that of `(2pi)/(lambda)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(1)/(lambda)=K=(2pi)/(lambda)`. So unit of `lambda^(-1)` is same as that of `(2pi)/(lambda)`.
