electromagnetic radition

radio waves

excites spin of nucleus (used in MRI - non invasive), responsible for am fm radio

microwaves

excites spin of electrons, excites rotation of h2o and fats around 12 cm to cook food

infrared

causes vibration in molecules, used in night vision goggles, excites wavelength of oh in ethanol, used to measure intoxication, paschen series

visible

excites valence electrons to higher energy level, solution for h atom balmer series, rays of detection for human eye, 300-700 nm

uv

excites valence electrons, lyman series for H emission, causes sun burns

x rays

excites core electrons, used in medicine for non invasive imaging, causes cell mutations so limit exposure

gamma rays

associated with decay of atom nucleus, emitted from stars hence cosmic ray name
