Photon spectrum
WebOct 28, 2024 · Photosynthetic photon flux - PPF (μmol/s) PPF describes how many photons the light generates in one second - the photon quantity is defined as micromole (μmol) within the Photosynthetically Active Range (PAR), which is 400-700nm. It can be calculated by a series of formulas with the spectrum. WebJan 30, 2024 · These packets of energy can be transmitted over vast distances with no decay in energy or speed. Photons travel at the speed of light, 2.997x10 8 m/s in empty space. The speed of a photon through space can be directly derived from the speed of an electric field through free space. Maxwell unveiled this proof in 1864.
