Longitudinal Wave (Compression Wave) wave particles vibrate back and forth along the path that the wave travels.
Compressions = The close together part of the wave (regions of high density). Rarefactions = The spread-out parts of a wave (regions of low density). Wavelength = the distance between successive rarefactions or successive compressions.
Transverse waves wave particles vibrate in an up- and-down motion.
Transverse Wave Description- Frequency ( f ) = the number of vibrations per unit of time made by the vibrating source. Units - cycles per second 1/s------Hertz (Hz)
Amplitude- Height of a wave, from the baseline to the crest or trough.
Wavelength ( )= Distance between adjacent crests in a transverse wave Distance a wave travels during one vibration - meters Units

Waves transfer energy without transferring matter. Frequency= waves/time
WAVE INTERFERENCE= when two waves meet while traveling along the same medium.
Constructive interference occurs when waves are in phase, that is when crests are superimposed and troughs are superimposed.
Destructive interference occurs when waves are out of phase, that is when crests are superimposed with troughs.
Electromagnetic Spectrum— Transfer of Radiation -- Transverse waves --They type of radiation is based on the waves wavelength and only the wavelength. --The spectrum from left to right decreases in Wavelength and increase in frequency and energy.
