In the above example, find phase difference `DeltaPhi`.
(a) of same particle at two different times with interval of 1 s ,
(b) of two different particle located at a distance of 10cm at same time

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
(a) `DeltaPhi=((2pi)/(T))Deltat`, but `(2pi)/(T) =omega=4.0 rad//s`
:. `DeltaPhi= omega Deltat=(4.0)(1.0)`
`=4rad`
`DeltaPhi=((2pi)/(lambda))Deltax`, but `(2pi)/(lambda)=k=0.02cm^-1`
:. `DeltaPhi=(0.02)(10)`
`=0.2rad`
