Two points are located at a distance of ...

Two points are located at a distance of 10 m and 15 m from the source of oscillation. The period fo oscillation is 0.05 s ad the velocity fo the wave is 300 `ms^(-1)` . What is the phase difference between the oscillations of two points?

A

`pi`

B

`pi//6`

C

`pi//3`

D

`2pi//3`

Text Solution

Verified by Experts

The correct Answer is:
D
Path difference `Deltax=x_(1)-x_(2)=15-10=5m`
`lambda = upsilonT=300xx0.05=15m`
`Deltaphi=(2pi)/(lambda).Deltax=(2pi)/(15)xx5=(2pi)/(3)`
