Question

According to the principle of superposition, when two waves meet, they ______.

Answer 1

Correct answer: D). Interfere

According to the principle of superposition when two or more waves meet the phenomenon of interference takes place. Constructive wave takes place when the waves join together so that they are in phase with each other.

Destructive interference is the type of interference that occurs when the waves come together in such a way that they completely cancel out with each other.

Hence, the correct answer would be option D.

Answer 2

When two waves they interfere. They pass through each other, and as they do so, the size of the resultant is equal to the sum of the sizes (amplitudes) of the waves involved.
