The phase difference which requires the minimum path length difference.
Explanation of Solution
Introduction:
A path length difference introduces a phase difference that can be observed for a monochromatic visible light.
Write the expression of phase difference
Here,
Since the phase difference is directly proportional to the path length difference therefore the minimum path length difference corresponds to the least phase difference of
Conclusion:
The smallest path length difference corresponds to the minimum phase difference of
Since a phase difference of
Since a phase difference of
The phase difference is directly proportional only to the path length difference at a constant wavelength of light. Thus, option
