Properties of Photon
Properties of a photon include:
- Photons are quantized particles, meaning they can only exist as discrete energy packets. This plays a fundamental role in the photoelectric effect and the emission and absorption of light by atoms and molecules.
- Photons are massless particles.
- Photons are neutral particles.
- Energy of a photon is directly proportional to its frequency, as described by Planck’s Equation
E = ℎν
where,
- ℎ is Planck’s Constant
- ν is Frequency
Photons carry momentum (p = h/λ) and can transfer it to other objects.
- Photons travel at the speed of light(c), approximately 3×108 meters per second in a vacuum. This constant speed is a fundamental aspect of Einstein’s theory of relativity.
- Photons show characteristics of both particles and waves. This is known as the wave-particle duality.
- Photons exhibit polarization. Polarization is the orientation of oscillations of electric and magnetic fields. Polarization can be linear, circular, or elliptical, depending on the orientations and phases of the fields.
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.
