WebThe realization that light beams can have quantized orbital angular momentum in addition to spin angular momentum has led, in recent years, to novel experiments in quantum mechanics and new methods for manipulating microparticles. Miles Padgett and Johannes Courtial are physicists at Glasgow University in Scotland. WebThe industry standard for measuring grow light efficiency is micromole per joule (sometimes written as umol/j, μmol/j, umolj-1 or PPF/W). That means that for every joule of electrical energy (joule = watt * second) a certain number of photon micromoles are produced. One micromole = 602,000,000,000,000,000. greg buckley cricket
