Photon energy - Wikipedia
https://en.wikipedia.org:443/wiki/Photon_energy
WEBPhoton energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy.

Atomic Energy Levels (video) | Khan Academy
https://www.khanacademy.org:443/science/physics/quantum-physics/atoms-and-electrons/v/atomic-energy-levels
WEBIn order to find the energy of the photon that was absorbed or emitted, you always take the higher energy level and subtract from it the lower energy level. So in this case, we would take -6eV, and subtract from it -10eV, which tells us that it would take a four eV photon to bump an electron up to that energy level, and the electron would emit ...

Electronic Energy Levels and Photons - Physics Book
https://www.physicsbook.gatech.edu:443/Electronic_Energy_Levels_and_Photons
WEBApr 25, 2022 · The Main Ideas. The Quantized Nature of Electronic Energy Levels. Electrons can be excited by absorbing energy from photons. Electrons can only be excited to certain electronic energy levels. Each electronic energy level is a number that represents the sum of the kinetic and potential energy (K+U).

WEBFeb 20, 2022 · A photon is a quantum of EM radiation. Its energy is given by E = hf E = h f and is related to the frequency f f and wavelength λ λ of the radiation by. E = hf = hc λ (energy of a photon) E = h f = h c λ (energy of a photon) where E E is the energy of a single photon and c c is the speed of light.

DOE Explains...Photons | Department of Energy
https://www.energy.gov:443/science/doe-explainsphotons
WEBPhotons travel in a wave-like fashion, in which the local electric and magnetic field oscillates in intensity, regularly swinging back and forth between high and low energy levels. The energy in the photons determines the type of electromagnetic radiation the photons transmit. This means low-energy photons carry radio waves.

PHOTON EMISSION AND ATOMIC ENERGY LEVELS
http://opencourse.uoregon.edu:80/pub/astr122/emission.html
WEBEphoton = hc/w. Thus the energy of a photon is inversely proportional to its wavelength. Short wavelength photons have more energy than long wavelength photons. The atom below is an idealized case. Its principal energy levels are indicated in units of Electron Volts. As a first step in this procedure do the following:
