Electromagnetic radiation

Electromagnetic radiation is the propagation of electrical and magnetic waves through space. The Scottish mathematician and physicist James Clerk Maxwell (1831 - 1879) has formulated the basic equations on which the entire classical electromagnetic theory is built.

Light, radio waves, X-rays and γ-radiation are all forms of this radiation. The waves are described by a wave length (λ) and a frequency (ν), the product of which is equal to the speed of light:

λ ν = c

Electromagnetic radiation can also be understood as a stream of photons ("light particles").
