Your question: How do you calculate electromagnetic radiation?

What is the formula for electromagnetic radiation?

Electromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E = h ν E=hnu E=hν , we have seen how the frequency of a light wave is proportional to its energy.

How do you calculate radiation energy?

The energy associated with a single photon is given by E = h ν , where E is the energy (SI units of J), h is Planck’s constant (h = 6.626 x 1034 J s), and ν is the frequency of the radiation (SI units of s1 or Hertz, Hz) (see figure below).

How do you calculate the energy of a photon of electromagnetic radiation at each of the following wavelengths?

The energy of a photon is given by the equation E=hν=hcλ E = h ν = h c λ . Here h is the Planck’s constant and c the speed of light in vacuum.

What is energy formula?

The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh. Unit. The SI unit of energy is Joules (J).

What is Stefan law of radiation?

Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. … The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.
