Superposition

Superposition occurs when two waves occupy the same point (the wave at this point is found by adding the two amplitudes of the waves).

Thumbnail
Interference

Interference occurs when multiple waves interact with each other, and is a change in amplitude caused by several waves meeting.

Thumbnail
Beats

The superposition of two waves of similar but not identical frequencies produces a pulsing known as a beat.

The Ear

The ear is the sensory organ that picks up sound waves from the air and turns them into nerve impulses that can be sent to the brain.

Applications: Ultrasound, Sonar, and Medical Imaging

Sound waves reflect off different materials differently (when the reflections are collected, they can provide information and images).
