Question

when the resultant wave has a greater amplitude than the original waves, the interference pattern is known as ____. constructive interference. destructive interference. total interference.

Explanation:

In wave interference, constructive interference occurs when two waves combine to form a resultant wave with a larger amplitude than the original waves. Destructive interference results in a smaller amplitude (or even zero), and "total interference" is not a standard term for this concept. So the correct option is the one with "constructive interference".

Answer:

A. constructive interference.
