The electron starts off in ground state (the lowest possible energy level), it then collides with a photon which is absorbed, increasing the energy of the electron, so it moves up to a higher energy level.
What is a photon? Question 1 options: A) an electron in an excited state. B) an electron that has been made electrically neutral. C) one form of a nucleon, one of the particles that makes up the nucleus. D) a small packet of electromagnetic energy that has particle-like properties. Click the card to flip 👆.
3 wrz 2018 · A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum (a completely empty space), have a constant speed of light to all observers.
7 sie 2016 · According to quantum electrodynamics, the most accurately verified theory in physics, a photon is a single-particle excitation of the free quantum electromagnetic field. More formally, it is a state of the free electromagnetic field which is an eigenstate of the photon number operator with eigenvalue 1.
This equation tells us: The higher the frequency of EM radiation, the higher the energy of the photon. The energy of a photon is inversely proportional to the wavelength. A long-wavelength photon of light has a lower energy than a shorter-wavelength photon.
Photons are massless particles that always move at the speed of light measured in vacuum. The photon belongs to the class of boson particles. As with other elementary particles, photons are best explained by quantum mechanics and exhibit wave–particle duality, their behavior featuring properties of both waves and particles. [2] .
