Two coherent sources separated by distance 
are radiating in phase having wavelength 
. A detector moves in a big circle around the two sources in the plane of the two sources. The angular position of 
interference maxima is given as
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Path difference at a point 
on the circle is
…… (i)
For maxima at 
, path difference should be integer multiple of wavelength
……… (ii)
From Eqs. (i) and (ii), we get
For 
Angular position,
