State what is meant by a photon

WebIn more precise terms a single-photon light beam is a number state with n = 1. That is, at any given time there will be exactly zero or one photon in a fixed time bin (typically the source lifetime or the excitation rate). In general terms, given a photon number state n 〉 one can calculate the expected g(2) ( τ ). Weblished by the establishment of the coherent state. 39.1 The Quantum Coherent State We have seen that a photon number states1 of a quantum pendulum do not have a classical correspondence as the average or expectation values of the position and momentum of the pendulum are always zero for all time for this state. Therefore, we have to seek a time-

WebFrançais A photon is a particle of light which essentially is a packet of electromagnetic radiation. The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle, this needs better wording, for 'fast electric field' and 'wiggle' ). The higher the frequency, the more energy the photon has. WebThe energy of the photon is the difference between the energy levels it transitions between. If the 3rd energy level is 𝐸 and the ground state is 𝐸 , then we can express the energy difference as the equation Δ 𝐸 = 𝐸 − 𝐸. The energy of 𝐸 is − 1. 5 1 eV and that of 𝐸 is − 1 3. 6 eV.

If the electron's in the ground state, it could absorb a four eV photon, or a six eV photon, or a seven eV photon. If the electron's at the second energy level, also called the first excited state, the electron could absorb a two eV photon or a three eV photon.
