Applications of Photons
Numerous technical uses exist for photons, a few of which are covered here:
- An significant use of photons is in lasers. Photon beams in a laser beam travel at the same wavelength and in the same direction. By passing the energised electrons via an optical gain medium, like glass or a gas, is accomplished.
- In design, engineers utilise Planck’s energy formula, E (= hv), to calculate the energy change resulting from photon absorption and to ascertain the frequency of light emitted from a specific photon emission.
- Single photon detection is used in a variety of hardware random number generators.
Photon
Photon is a fundamental particle of electromagnetic radiation. It is a quantum of light and other electromagnetic waves. It is the force carrier of the electromagnetic force. Photons can display wave-like behaviors such as interference and diffraction. They can also exhibit particle-like behaviors such as the photoelectric effect. This is known as wave-particle duality.
Photons carry momentum and travel at the speed of light. Photons are produced through processes such as electron transitions in atoms, particle interactions, and particle-antiparticle annihilation. In the photoelectric effect, photons transfer their energy to electrons in a material, leading to the emission of photoelectrons.
