Questions: 20 | Attempts: 10 | Last updated: Mar 13, 2026

Sample Question 1
Wave interference happens when:

A wave stops completely

Two or more waves overlap in the same region

A wave changes colour

A wave becomes a particle

Sample Question 2
The principle that overlapping waves add their displacements is called superposition.

True

False

Sample Question 3
Constructive interference occurs when waves overlap:

Completely out of phase

In phase (crest with crest, trough with trough)

At different speeds only

Only in water waves
