Does a … WebA laser pointer typically has a power rating of 1 mW, or 0.001 Joules per second. This means that every second a laser pointer emits a number of photons equal to (3.2x10 18 photons/J)(0.001J/s) = 3.2x10 15 photons/s. Now that we know how many photons are produced per second, we need to know how much momentum is carried by each photon.

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 … Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy. Photon energy can be expressed using any unit of energy. Among the units commonly used to d… WebIt was originally defined as the energy in one mole of photons ( 6.022 × 1023 photons). [1] [2] Because energy is inversely proportional to wavelength, the unit is frequency dependent. This unit is not part of the International System of Units (SI) and is redundant with the joule. forwards and futures compare and contrast
