Used for transmitting TV programmes
wavelength = 1m to 3 x 10^3m
(wavelength = 1m to 0.003m)
Used for transmitting phone calls and for cooking.
wavelength = 10^-3m to 1m
(wavelength = 0.001m to 1m)
Detected by skin, used for communication in optical fibres.
wavelength = 4 x 10 -7m to 4 x 10 -3m
(wavelength = 0.0000004m to 0.003m)
Detected by eyes and cameras
wavelength = 7 x 10 -7m to 4 x 10 -7m
(wavelength = 0.0000007m to 0.0000004m)
Causes suntans and may cause skin cancer
