Photons are known to be chargeless massless... However, since they travell with reletivistic velocity, they gain mass.
A photon has zero electrical charge.
A photon is a massless particle, so it does not have a rest mass. It only possesses energy and momentum, but in the context of special relativity, mass is not a property of a moving photon.
Photon spin is a fundamental property that affects how photons interact with matter. In quantum mechanics, the spin of a photon determines its polarization and angular momentum, which are crucial for understanding phenomena like light-matter interactions and quantum entanglement. Understanding photon spin is essential for developing technologies such as quantum computing and communication.
The rest mass of a photon is considered to be zero because photons are massless particles. They travel at the speed of light in a vacuum and do not possess rest mass. This is a fundamental property of photons in the Standard Model of particle physics.
Among others: mass zero; electric charge zero; stable (it doesn't decay); it can only move at the speed of light.
A packet of light energy is called a photon.
That simply means that light has energy. Every individual piece of light (photon) carries a small amount of energy.
The opposite of a photon is an antiphoton.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
Photon flux can be calculated using the formula: photon flux = v * E, where v is the frequency of the photons and E is the energy of each photon. By multiplying the frequency of the photons by the energy of each photon, you can determine the photon flux.
