To Explain: The difference of path length when two rays of light from the same source destructively interfere.
Answer to Problem 7Q
Because of destructive interference, the path lengths differ by odd half-integer multiples of the wavelength.
Explanation of Solution
Introduction: The pattern resulting from superimposing of two waves is known as interference. Interference can be destructive or constructive.
Destructive interference occurs when the crest of a wave overlaps the trough of another wave. Also, this happens when path length change by odd half integer multiples of
Conclusion: When the crests and troughs match-up, destructive interference occurs.
