Question	Answer
Electromagnetic spectrum	Radio waves (longest/ lowest frequency) Microwaves Infrared Visible Ultraviolet X-Rays Gamma rays (shortest/ highest frequency) All are transversal

The Wave Equation	Wave speed (m/s) = Frequency (Hz) x Wavelength (m)
Longitudinal waves	Vibrates forwards and backwards Compressions is where the waves move closer together and rerefractions is where the waves move further apart E.G. Sound
Transversal Waves	Vibrates up and down E.G. Light
The Doppler Effect	sound waves bunch together as they head towards you so they sound high pitched sound waves spread out after they go past you so they sound low pitched
Sound waves	Vibrations of air particles Longitudinal Cannot be heard in a vacuum
