The wave number of the photon is the number of waves per unit distance cm -1 or m -1. So, the greater the wavelength of a photon, the smaller the energy associated with a photon. The wavelength and frequency of a photon are inversely proportional to each other. Since the wavelength of a photon is very very small, so it is expressed in Ao, nm, or pm. The wavelength of a photon is the distance between two adjacent crests or troughs. In such a way the ratio of these two quantities is always constant. The value of the energies and the frequencies of photons are adjusted by nature. When the energy of a photon is taken in joules It is the ratio of the energy of a photon to the frequency of that photon. The frequency of the photon (v) is the number of waves produced per second.Īll the photons of light have the same velocity so their energies depend upon their frequency is measured in wave/sec, cycle/sec, or S -1 or Hertz (1 cycle/sec =1 Hz) ‘E’ is the energy of the photon is ergs or joules. The energy associated with a photon is given by the formula.These packets of energies are called photons or quanta. Light is emitted or absorbed in the form of packets of energy.Light is not emitted or absorbed continuously. This theory is called Plank’s quantum theory. In 1900, Max Planck gave his theory about light. The German physicist Max Planck came up with a theory of the quantized nature of the energy of waves.Įvidence for a particle theory of energy, radiation, black body radiation, and quantum theory of radiation are some of the topics discussed in this article. The photoelectric effect can’t be explained by classical theory or classical mechanics according to scientists by the 20th century. James Clerk Maxwell, a Scottish physicist, gave the equations used to define the properties of radiant energy in 1873. Matter and energy used to be separate from one another. Applications of Planck’s Quantum Theoryīy the end of the 19th century, scientists were able to explain most natural phenomena by using classical theory.Evidence in Support of Planck’s Quantum Theory.
