A) the same in both the regions of constructive interference and the regions of destructive interference.
B) greater in regions of constructive interference than in regions of destructive interference.
C) smaller in regions of constructive interference than in regions of destructive interference.
D) unchanged in regions of destructive interference but greater in regions of constructive interference.
E) unchanged in regions of destructive interference but smaller in regions of constructive interference.

Question

Quizplus · Accepted Answer

In an interference pattern, the wavelength and frequency of the waves remain constant throughout the entire pattern, regardless of whether they are in regions of constructive or destructive interference. This is because both constructive and destructive interference depend on the relative phase of the waves, not their properties. Therefore, the best choice is A, which states that the wavelength and frequency are the same in both types of interference regions.
