Two or more waves combining to produce a wave with a smaller displacement is called _____. A. constructive diffraction

B. constructive interference

C. destructive interference

D. destructive diffraction

Answers

Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .

What is the definition of destructive interference?

Destructive interference happens when the maxima of two waves are 180° out of phase a positive displacement of one wave is canceled exactly by a negative displacement of the other wave.

The formula for brighter patches resulting from constructive interference and darker patches resulting from destructive interference in a diffraction grating is:

$\rm d sin \theta = n \lambda$

Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .

Hence, option C is correct.
