Question

What is the difference and a similarity between constructive interference and destructive interference?

Answer 1

In constructive interference, waves that are in phase will combine together and increase the amplitude. In destructive interference, waves are out of phase and cancel one another out.

When two waves occupy the same point, superposition occurs. ... Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves. Destructive interference is when two waves superimpose and cancel each other out, leading to a lower amplitude.
