Resource summary

Question Answer
Electromagnetic spectrum Radio waves (longest/ lowest frequency) Microwaves Infrared Visible Ultraviolet X-Rays Gamma rays (shortest/ highest frequency) All are transversal
Amplitude Wavelength Peak Trough
Incidence Ray Reflected Ray
Refraction of Light
Pitch and Amplitude
Diffraction
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
