It is found that what waves of same intensity from two coherent sources superpose at a certain point, then the resultant intensity is equal to the intensity of one wave only. This means that the phase difference between the two waves at that point is

A

zero

B

`pi/3`

C

`(2pi)/3`

D

`pi`

Text Solution

Verified by Experts

The correct Answer is:
C
Intensity, `I=4I_(0)"cos"^(2)phi/2`
`because I=I_(0)`
`:. phi=(2pi)/3`

Assertion: Two identical waves due to two coherent sources interfere at a point with a phase difference of (2pi)/3 , then the resultant intensity at this point is equal to the individual intensity of the sources. Reason: A phase difference of (2pi)/3 is equivalent to a path difference of lambda/3 .
