What is the energy (in J) of 1 mole of the photon? - Wyzant

WebThis term is based on the number of photons in a certain waveband incident per unit time (s) on a unit area (m2) divided by the Avogadro constant (6.022 x 10 23 mol-1). It is used commonly to describe PAR in the 400-700 nm waveband. Definition Source: Thimijan, Richard W., and Royal D. Heins. 1982. The daily light integral (DLI) is the number of photosynthetically active photons (photons in the PAR range) accumulated in a square meter over the course of a day. It is a function of photosynthetic light intensity and duration (day length) and is usually expressed as moles of light (mol photons) per square meter (m ) per day (d ), or: mol·m ·d . DLI is usually calculated by measuring the photosynthetic photon flux density (PPFD) in μmol·m ·… rco grant awards https://ods-sports.com
