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

(a) `20m//s`

B

(b) `5m//s`

C

( c ) `2000m//s`

D

(d) `5pim//s`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) From equation given,
`omega = 100` and `k = 20`, `v = (omega)/(k) = (100)/(20) = 5m//s`
