Question

A marine biologist is studying dolphin calls and notices that sometimes the calls sound louder based on the background noise in the water. She concludes that the sound waves are adding together. What type of wave interference does this describe?

Constructive
Dismissive
Destructive
Refractive

Answer 1

It would be constructive since the waves are joining each other.

Answer 2

The right option is Constructive

This describes the constructive wave interference.

The constructive wave is a type of interference that is formed when the crests of two interfering sound waves that are moving toward each other in the same medium meet in the same spot, which result in the combination of their amplitudes to form bigger amplitude that is much larger than the amplitude of a single wave. From the question, the addition of the sound waves describes the constructive wave interference.
