Light-energy relations | Formulas

In the focus from the green LED it is possible to find a set of formulas that establish various relations between light and energy.

First, we have to Wien's displacement law of the formula that relates the wavelength (where is located the maximum emission of electromagnetic radiation of black body) and the temperature.

Second, it can be find the Stefan-Boltzmann law for calculating the brightness of a particular body.

Subsequently, there is the presence of Planck's relationship which is used for quantifying the electromagnetic energy.

Finally, there is the famous law of mass-energy equivalence, Einstein, which relates the energy of a body with its mass and speed of light in vacuum.

Thus, this location in the poster possesses extensiva range of formulas that establish relationships between light (energy) and matter.
