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


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


The highest point of a wave


The lowest point of a wave


The maximum distance that the particles of a wave's medium vibrate from their rest position


The Distance from any point on a wave to an identical point on the next wave


In physics, the time that it takes a complete cycle or wave oscillation to occur


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


The bouncing back of a ray of light,sound or heat when the ray hits a surface that it does not go through


Bending of wave as it passes through an opening


The bending of light as it passes through a medium


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


Wiggle in time, No net movement


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


Reflection is inverted


Reflection is identical


Point of Destructive interference


Point of Constructive interference
