Two waves of equal amplitude meet and cancel each other at a point. What is this called?
Answer and explanation
Correct answer: C. Destructive interference
- Step 1: When the crests of one wave meet the troughs of the other, the displacement cancels.
- Step 2: This is destructive interference.
Answer
Destructive interference.
Why not the others: Constructive interference adds the waves, diffraction is spreading and resonance is a large response at a natural frequency.
