Results from waves colliding out of phase to produce a wave with a smaller amplitude, resulting in a softer sound or even silence.

Generated when continental plates collide, pull apart, or slide against each other; it produces waves that can be used to determine the structure of Earth's interior.

The number of waves that pass over a given amount of time; measured in Hertz (Hz).

The frequency of a vibrating object that is required to generate a standing wave; musical instruments are built to vibrate at these frequencies.

A type of wave that results from particles moving parallel to the direction the wave is moving.

Faster longitudinal waves produced by an earthquake slow down as they move deeper into the earth, suggesting the Earth has a liquid outer core.

When one object, vibrating at a harmonic of a second object, forces the second object into vibrational motion.

Slower transverse wave produced by an earthquake; unable to travel through liquids; reflected as it moves deeper into the Earth, suggesting that the Earth has a liquid outer core.

Results from particles in the air vibrating and colliding with one another in a longitudinal wave pattern, which are ultimately received by your ear.

A vibrational pattern is created within a medium when the vibrational frequency of the source causes reflected waves from the source.

A type of wave that results from particles moving at right angles to the direction the wave is moving.

Maximum movement of a wave below its rest position.

Represents the relationship between the velocity, wavelength, and frequency of a wave; 𝑣=𝑓𝜆

The distance from the rest position of a wave to its crest or trough.
