When two waves are out of phase by ________ wavelength, they produce destructive interference, canceling each other's amplitude and resulting in contrast in the image.
A) one-tenth of a
B) one-eighth of a
C) one-quarter of a
D) one-half of a
E) one

Quizplus · Accepted Answer

When two waves are out of phase by one-half of a wavelength, they are in complete opposition to each other. This phase difference causes the peaks of one wave to align with the troughs of the other, resulting in destructive interference where the waves cancel each other out.
