The displacement y of a particle in a medium can be expressed as `y = 10sin[100 t + 50x + pi/4].` . The speed of the wave is

A

`20 m//s`

B

`2 m//s`

C

`3 m//s`

D

`5 pi m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`omega = 100 , K = 50`
velocity of waves = `omega/K implies (100)/(50) = 2 m//s`
