Electromagnetic Spectrum
Radio
properties: biggest wavelength, lowest frequency, can be reflected, wavelength: > 1 mm
-
-
Transverse wave 
-
Infrared
risks: eye damage (in large doses), skin damage (in large doses), heating
properties: frequency that is absorbed by chemical bonds -> heating, all objects emit this, wavelength: 1,000µm - 760 nm
uses: electrical heaters, cookers for cooking food, infrared cameras
Microwave
properties: heating, can pass through atmosphere, wavelength quite large (smaller than radio), wavelength: 1 mm - 25 μm
uses: cooking food and satellite communications
risks: heat body tissue, very low risk
Visible
Properties: Seen by human eye (colours eg red blue), wavelength: 750 nm - 400 nm
Uses: fibre optic communications
risks: generally harmless, but highly concentrated rays can damage eye cells/ cause burns
UV
properties: low power of penetration, ionising radiation, wavelength: 400 nm - 1 nm
uses: sterilising water, help skin make vitamin D
-
X ray
properties: highly penetrating, ionising radiation, wavelength: 1 nm - 1 pm
-
risks: increased risk of cancer, high level of radiation can lead to fainting and hair loss
Gamma ray
-
properties: highly penetrating, ionising radiation, wavelength: < 10^-12 m
risks: cause cancer, damage living cells, gene mutations
