MMS Waves

MMS Waves - Sound and Electromagnetic

Amplitude size of the wave, up and down (larger amplitude = louder sound or brighter light)
Intensity loudness - depends on the amplitude (larger amplitude = louder sound)
decibel (dB) unit used to measure sound
frequency how many waves pass in one second (how fast waves are traveling)
pitch the highness or lowness of a sound
velocity the speed and direction
tone quality what the tone sounds like (2 sounds can be different but still have the same pitch and loudness)
noise sound that has no set pitch or regular wave pattern, is often unpleasant
longitudinal wave also called compression wave. particles move side to side (like a spring) Sound moves this way
transverse wave particles move up and down creating a wave shape - light travels this way
reflection when waves hit something and bounce back - Example - light hits a mirror and bounces back or sound hits a canyon wall and echos
refraction waves bend because they are slowing down - Example - Light moving in air into water slows down when it hits water and bends
trough the bottom of a transverse wave
crest the top of a transverse wave
wavelength the distance between 1 wave and the next (1 full wave)
transmit let light or sound pass through (like a window)
absorb to take in (black absorbs all light)
