A wave is represented by the equation `y=0.5 sin (10 t-x)m`. It is a travelling wave propagating along the + x direction with velocity

A

5 m/s

B

10 m/s

C

20 m/s

D

15 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`y = 0.5 sin (10 t - x)`
Comparing with `y = a sin (omega t - Kx)`
We get `omega = 10 and K = 1`
`:.` Velocity of the wave `= (omega)/(K) = (10)/(1) = 10 m//s`
