Antinode

When two waves interfere constructively the point with the queatest displacement

Transverse wave

A transverse wave travels in a direction perpendicular to its displacement.

Longitudinal wave

A wave in which the disturbance is parallel to the direction of travel.

Amplitude

The maxium distance an object in simple harmonic motion moves from equilibrium.

Trough

The lowest point of a Transverse wave.

Wavelength

The shortest distance between two points where the wave pattern repeats.

Frequency

The number of complete oscillations a wave makes each second is frequency of the wave.

Interference

Interference occurs when more than one wave moves through the same medium at the same time.

Node

When waves are superposed, any point that does not experience displacement.

Periodic motion

Any motion that repeats in a regular cycle.

Period

The time needed for an object to complete one full cycle of simple harmonic motion.

Wave

A disturbance that carries engergy through matter or space.

Refraction

Refraction refers to the change in direction waves experience at the boundary between two different media.

Crest

The highest point of a transverse wave.
