The displacement y of a wave travelling ...

The displacement `y` of a wave travelling in the x-direction is given by
`y = 10^(-4) sin ((600t - 2x + (pi)/(3))meters`
where `x` is expressed in meters and `t` in seconds. The speed of the wave-motion, in `ms^(-1)`, is

A

200

B

300

C

600

D

1200

Text Solution

Verified by Experts

The correct Answer is:
B
`y = 10^(-4) sin (600t - 2x +pi//3)`
Speed of wave motion `= (omega)/k = 600/2 = 300m//s`
