For other topics related to Einstein see Einstein (disambiguation).''-----An einstein is a physical unitunit used in irradiance and in photochemistry. One einstein is one Mole (unit)mole of photons, regardless of their frequency. Therefore, the number of photons in an einstein is Avogadro's number. Irradiance can be measured in einsteins per square metre per second.The einstein is used in studies of photosynthesis since the light requirement for the production of a given quantity of oxygen is a fixed number of photons (about nine einsteins per mole of oxygen formed), regardless of the frequency of the light.It is named in honour of Albert Einstein, who explained the photoelectric effect and introduced the idea of light quanta, now called photons, in a 1905 paper.Photosynthetically active radiation (PAR) is usually reported in microEinsteins per second per square metre,one microEinstein being one-millionth of an einstein.Category:Units of amount of substanceCategory:Albert Einsteinde:Einstein !(Einheit)ja:アインシュタ イン?
