All are electromagnetic waves
They differ mainly in wavelength, frequency and photon energy.
Visible light is a small band
Human vision responds to only a limited wavelength range.
Wavelength and frequency are linked
In vacuum, longer wavelength means lower frequency.
Different bands reveal different information
Astronomers use many wavelengths because matter emits, absorbs and scatters them differently.
