SP4+% Waves and EM Spectrum

Question	Answer
waves	transfer energy + information without tranferring matter
oscillations	periodic motions at a certain frequency
medium	the substance, material or vacuum that a wave travels through
transverse waves	the oscillations are perpendicular to the direction of energy transfer
longitudinal	the oscillations are parallel to the direction of energy transfer
compression	areas of high pressure/concentration in a wave
rarefaction	areas of low pressure/concentration in a wave
frequency	the number of complete waves passing a point per second no. of waves / time
time period	the time taken for a complete wave to pass a point 1 / frequency
wavespeed	speed at which the peaks of the wave travel distance / time frequency * wavelength
primary waves	-longitudinal -faster -travels through solids/liquids -\|\|\|\|\|\|
secondary waves	-transverse -slower -only travels through solids -/\/\/\/\
pitch	-determined by frequency -vibrates eardrum at a certain frequency
volume	-determined by amplitude -vibrates eardrum at a certain amplitude
pinna	acts as a funnel to collect soundwaves
