Answer:
Find the answer in the explanation
Explanation:
If Two rays of light from the same source destructively interfere, their path lengths will differ by ( n + 1/2) wavelength
For destructive interference, the path difference is an odd number of half wavelength.
Effect of interference of light are:
1.) Haloes of light around street lamps
2.) The moon on a foggy night
3.) Light and dark bands of light.
