<h3>What is constructive interference?</h3>
- It refers to the phenomenon where two identical waves come into contact with each other and create a new wave that is twice as amplified as their individual amplitudes.
When the waves from the friends on opposite sides reached each other in the middle, they produced more amplified waves that then raised the child in the middle of the pool higher.
