A parallel beam of light of wavelength 
is incident normally on a narrow slit. A diffraction pattern formed on a screen placed perpendicular to the direction ofthe incident beam. At the second minimum of the diffraction pattern, the phase difference between the rays coming from the two edges of slit is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
: For the second minimum,
Path difference 
Therefore, corresponding value of phase
difference is
Path difference
