Medium
A physical environment in which phenomena occur
Mechanical Wave
A wave that requires a medium through which to travel
Electromagnetic Wave
A wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
Sphere
A three-dimensional surface whose points are equally distant from the center; a globe
Transverse Wave
A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
Longitudinal Wave
A wave in which particles of the medium vibrate parallel to the direction of wave motion
Crest
The highest point of a wave
Trough
The lowest point of a wave
Amplitude
The maximum distance that the particles of a wave's medium vibrate from their rest position
Wavelength
The Distance from any point on a wave to an identical point on the next wave
Period
In physics, the time that it takes a complete cycle or wave oscillation to occur
Frequency
The number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time
Doppler effect
An observed change in the frequency of a wave when the source or observer is moving
Reflection
The bouncing back of a ray of light,sound or heat when the ray hits a surface that it does not go through
Diffraction
Bending of wave as it passes through an opening
Refraction
The bending of light as it passes through a medium
Interference
the combination of two or more waves that results in a single wave
Constructive Interference
A superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves
Standing Wave
A pattern of vibration that simulates a wave that is standing still
Destructive Interference
A superposition of two or more waves that produces an intensity equal to the difference of the intensities of the individual waves
Vibration
Wiggle in time, No net movement
Wave
Wiggle in time and space, Net movement of wave, Created by vibration
Surface wave
Only appear on surface of 2 medians, particles move parallel and perpendicular to wave direction
Origin Line
Line of equilibrium
Fixed
Reflection is inverted
Free
Reflection is identical
Node
Point of Destructive interference
Antinode
Point of Constructive interference
