Question

Which occurs when two or more waves combine to produce a wave with a larger displacement?

A. refraction

B. constructive interference

C. destructive interference

D. diffraction

Answer 1

B

Step-by-step explanation:

Constructive interference occurs when two or more waves combine. It creates a larger displacement and amplitude.

Answer 2

B.Constructive interference.

Step-by-step explanation:

Two or more waves combines to produce a wave with a larger displacement and amplitude is because of constructive interference. Constructive interference takes place when maxima of two waves(in the same phase) added together to produce larger amplitude. When an integer numbers of waves constructively interfere we get a pattern of alternatively bright and dark band.
