Exam-style question
Try this first
When two waves meet and create a larger amplitude, what is this phenomenon called?.
- A.Destructive interference
- B.Constructive interference
- C.Refraction
- D.Diffraction
Model answer
What a good answer should say
- Constructive interference
Explanation
Why this works
Constructive interference occurs when two waves meet in phase, resulting in a larger amplitude. This is a direct application of the principle of superposition, where the displacements add together.
