UltrafastPED said:There may be many excitation modes; the different modes represent different energies.
The quantum of excitation in QED (quantum electrodynamics) is known as a photon. It is a fundamental particle that carries electromagnetic energy and interacts with charged particles.
The quantum of excitation, or photon, is responsible for carrying the electromagnetic force between charged particles. It is exchanged between particles during interactions, such as absorption, emission, and scattering.
Yes, the quantum of excitation, or photon, can exist on its own as a free particle. It can also be created and destroyed in interactions with other particles.
In quantum field theory, the quantum of excitation is seen as a fluctuation in the underlying quantum field. These fluctuations are responsible for the behavior and interactions of particles in the theory.
The quantum of excitation theory in QED explains the behavior of light as a wave-particle duality. It can exhibit properties of both a wave and a particle, depending on the experimental setup. This duality is also seen in other quantum phenomena, such as the double-slit experiment.
