The highest point of a wave
Crest
The heigth of a wave
Amplitude
A wave in which the disturbance moves perpindicular to the direction the wave travels
Transverse wave
A wave vibrating in the direction of propagation
Longitudinal wave
A substance that makes it possible to transfer energy from one location to another
Medium
The meeting or combining of waves
Interference
A system of waves spread out as a result of passing through a narrow aperture or across an edge
Diffraction
A wiggle in time
Vibration
SI unit of frequency
Hertz
When two waves meet and their crests line up together
Constructive interference
A single disturbance that travels through a medium
Wave pulse
A point at which lines or pathways intersect
Nodes
A vibration of a system in which some points remain fixed while others vibrate with a maximum amplitude
Standing wave
The position of maximum displacement in a standing wave system
Antinodes
The time it takes to complete a whole cycle
Period
A wave formed by the vibrations of electric and magnetic fields
Electromagnetic wave
Diminution in the density of some thing
Rarefaction
A seismic wave that travels along or parallel to the earths surface
Surface wave
The central part of the theory of quantum mechanics
Matter wave
The number of waves that pass a fixed point in a given amount of time
Frequency
The lowest point of a wave
Trough
A wave that is an oscillation of matter and therefore transfers energy through a medium
Mechanical wave
The throwing back by a body or surface
Reflection
The fact or phenomenon of light
Refraction
The speed at which a wave travels
Wave speed
The action of compressing or being compressed
Compression
When the crest of one wave meets the trough of another
Destructive interference
The distance between the crests of a wave
Wavelength
Motion repeated in equal intervals of time
Periodice motion / SHM
A state in which opposing forces or influences are balanced
Equilibrium
The property that is transferee in a wave
Energy
An oscillation accompanied by a transfer of energy
