Electromagnetic spectrum
An idealised body that is able to absorb all electromagnetic radiation that falls on it.
Electromagnetic radiation which includes visible radiation and radiation that cannot be seen by the human eye such as infrared radiation.
Classical Theory
Quantum theory
Electromagnetic spectrum may be a:
The dispersion of white light by a prism consisting of seven visible colours.
Produced by an excited atom is a series of colored lines with unique wavelengths and frequencies.
\(E=hf\),
where \(h\) = Planck constant (\(6.63\times10^{-34} \text{ J s}\)
\(f\) = frequency of light waves
\(\lambda = \dfrac{h}{mv}\),
where \(m\) = mass of particle,
\(v\) = velocity of particle
