Question

The equation of a wave is given by
`y = a sin omega [(x)/v -k]`
where ` omega ` is angular velocity and v is the linear velocity . The dimensions of k will be
A. `[T^(2)]`
B. `[T^(-1)]`
C. `[T]`
D. `[LT]`

Answer 1

Correct Answer - C
`omega k` is dimensionless
` [k] = [(1)/(omega)] = [T]`
