# How is a photon produced? ### How is a photon produced?

In quantum field theory, the photon is the mediating particle of the electromagnetic interaction….It is however possible to produce of the photons one by one through the following processes:

1. electronic transition;
2. nuclear transition;
3. annihilation of particle-antiparticle pairs.

### How to create two entangled particles?

In addition: it is very easy to to create of the entangled particles. A simple collision between two particles (broadcast) gives two entangled particles.

### How to explain the entanglement?

L’entanglement is a quantum phenomenon in which two or more particles share the same properties. When we measure the state of one of them, the other entangled particles instantly take on the same value, independently of the distance between them.

### How to isolate a photon?

To do this, an ion in its lowest energy level is sent a laser pulse which puts it halfway in energy between this level and the one just above. The ion between the two energy levels has an equal probability of going to one level or the other, it is in a superposition of these two states.

### Why are photons absorbed?

an electron is in a state of energy, here named . If a photon brings it exactly the energy corresponding to the energy difference with a state , then the photon is absorbed by the atom, and the electron makes a transition .

### What is the spin of the photon?

Protons and neutrons also have a spin 1/2, the photon a spin 1, p mesons a spin 0, etc The directions of the spin Also are quantified: there can only be 2s + 1 for one spin s; so, the spin of the electron can take only 2 × 1/2 + 1 = 2 orientations.

### What is the difference between photon and photon?

The base “photo-” is taken from the ancient Greek φῶς, φωτός (phôs, phōtós) which means “light”. The suffix “-on” is taken from the end of “electron”. “Photon” designates the particles carrying light and the associated energy.

### What is Photon

The modern term “photon” is derived from the Greek word meaning “light”, φῶς, φωτός (transliterated phos, pictures). It designates the particles carrying light and the associated energy.

### What is the first image we have of the photon?

The first image that we have of the photon is the “ball of light”, the light would be composed of grains which would travel at 2 m/s (speed of light). In this model, a given light energy flux is broken down into balls whose energy depends on the wavelength λ and is equal to h. c/λ.

### How to calculate the energy of a photon?

absorption (stimulated): a photon which has exactly the right energy is sent to the electron of an atom; the latter absorbs the photon and thus stores its energy, which allows it to go to the upper level (level E 2) from the lower level (level E 1 ). The energy of the photon will be: E photon = E 2 − E 1 = h × v.
