Question

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

Answer 1

Answer:
Destructive interference

Step-by-step explanation:
Interference is a term used to refer to the combination of two waves or their overlap
There are two types of interference:
1- Constructive interference: This happens when the waves overlap/combine to produce a resultant wave with a larger displacement
2- Destructive interference: This happens when the waves overlap/combine to produce a resultant wave with a smaller displacement

Hope this helps :)

Answer 2

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

Step-by-step explanation:

The interference of 2 waves of equal frequency and opposite section, leading to their cancellation wherever the negative displacement of 1 perpetually coincides with the positive displacement of the opposite.

In harmful interference, the crest of 1 wave meets the trough of another, and therefore the result's a lower total amplitude.
