Webb27 feb. 2016 · Planck theorized that electromagnetic radiation can only exist as “packets” of energy, later called photons. The constant, h, which is named for Planck, is a mathematical value used to calculate photon energies based on frequency. The energy of the electromagnetic spectrum ranges from 10-12 to 10 10 eV. WebbRadiation is defined as the emission and transfer of energy via high-energy particles (photons) or electromagnetic waves. In fact, the vast majority of radiation that you encounter on a daily basis has nothing to do with nuclear radiation at all. From an everyday light-bulb, to the microwave that heats your frozen lunch, to the radio that you ...

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. Photons travel at the vacuum speed of light (more commonly just called the … richardine roessler
