A wave is travelling along X-axis. The disturbance at x=0 and t=0 is `A//2` and is increasing. Where A is amplitute of the wave. If `y=A sin(kx-omegat+emptyset)`, deetemine the initial phase `empyset`.

A

`(pi)/(6)`

B

`(5 pi)/(6)`

C

`(pi)/(3)`

D

`(11 pi)/(6)`

Text Solution

Verified by Experts

The correct Answer is:
B
At `t = 0, x = 0`
`(A)/(2) = A sin phi rArr phi = (pi)/(6), (5pi)/(6)`
since, `(dy)/(dt)` is positive for `phi = (5pi)/(6)`
