Wave a transfer of energy without a transfer of matter
Energy ability to do work
Medium a material through which waves can travel (solid, liquid, or gas)
Mechanical Waves can only travel through a medium
Electromagnetic Waves can travel through a medium or through empty space
Vibration a repeated up-and-down or back-and-forth motion
Transverse Waves motion occurs perpendicular(like a snake) to the direction of travel (mechanical or electromagnetic)
Crest the high point on a transverse wave
Trough the low point on a transverse wave
Compressional Wave motion is parallel to the direction of travel (only mechanical)
Compression amount of energy is greater because molecules are close together
Rarefaction amount of energy is smaller because molecules are spread out
Amplitude half the distance between a crest and a trough
Wavelength the distance between two adjacent crests or two adjacent troughs
Frequency number of wavelengths that pass by a point each second
Reflection wave bounces back
Refraction the bending of a wave
Defraction the bending of a wave around an object
Absorbtion wave is absorbed by the medium
Emit wave is produced
Transmit wave is moved
Transparent see through
Translucent foggy
