Question

what is path difference​

Answer 1

Explanation:

path difference is the difference in path traversed by the two waves , measured in terms of wavelength of the associated wave. ... Whereas, if path difference b/w 2 waves is odd multiple of half wavelength, it satisfies condition for destructive interference.

Answer 2

Answer:

here's your solution.

Path difference is the difference (in meters) between the lengths of two paths. When two waves have the same frequency, and travel at the same velocity, and travel the same distance they will keep the same phase difference.
