Medium a physical environment in which pnemonea 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 of which radiate outward at the speed of light.
Transverse waves a wave in which the particles of the medium move perpendicular to the direction the wave is traveling.
Longitudinal wave a wave in which the particles of the median vibrate parallel to the direction of the 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 waves medium vibrate from their rest position.
Wavelength the distance from any point on a wave to an identical point on the next wave.
Period the time that it takes a complete cycle or wave oscillation to occur.
Frequency the number of wavelengths that pass a point in a given time interval.
Doppler effect occurs for light and other types of waves.
Reflection is simply the bouncing back of a wave when it meets a surface or boundary.
Diffraction this bending of waves as they pass an edge.
Interference when several waves are in the same location the waves combine to produce a single new wave that is different from the original.
Destructive interference a wave whose amplitude is the sum of the amplitudes of the two individual waves.
Standing waves can form when a wave is reflected at the boundary of a medium.
