Question

The equation of a wave is given by :

y=Asinø(x/v-k)



where ø is the angular velocity and v is the

linear velocity. The dimension of k is :

(A) LT (B) T

(C) T

–1

(D) T

2​

Answer 1

Answer:

Correct option is

B

[T]

vx have the same dimension as of k.

∴Dimension formula of k=[LT−1][L]=[T]
