The displacement `y` of a partcle in a medium can be expressed as,
`y = 10^(-6) sin ((100t + 20x + (pi)/(4))m` where `t` is in second and `x` in meter. The speed of the wave is

A

`2000m//s`

B

`5m//s`

C

`20m//s`

D

`5pim//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`v=(co-efficent of t)/(co-efficent of x)=(omega)/(k)=(100)/(20)=5 m//s`
