Solution
- The two sources of light must be coherent.
- The two sources of light must be monochromatic.
- The two interfering waves must have the same amplitude.
- The two slits should be narrow.
- The two waves should be in the same state of polarization.
- The two light sources should be closely spaced and the distance between the screen and the sources should be large.
