In photochemical reaction we have photons that passed to the surface starting photochemical reaction - producing some electrons.
quantum yield=produced electrons/passed photons.

What is a photosynthetic reaction in a plant cell transforming energy from sunlight into chemical energy?
Photosynthesis. In the process of photosynthesis, light energy is used to convert carbon dioxide and water into glucose (sugar) and oxygen. The energy in the light is converted into the chemical energy in the glucose molecules.
How is light energy converted to chemical energy?
Via photosynthesis, plants have developed unique photo-sensitive system that permit them to take the sunlight and convert it. This energy is converted into chemical energy which is stored as food inside the plant.
Could you say that the dark image on the photographic film is due to fluorescence why?
no, photographic films contains silver iodide which converts to gray-black metallic silver via photo reduction. Photo reduction is a light-dependent reaction which converts solar energy to chemical energy. when UV rays or visible light (basically sun rays) interacts with the silver chloride in the photographic film, photo reduction takes place. try pouring some silver chloride on a piece of white cloth, then leave it out in the sun, the area where the silver chloride is exposed to the sun will become dark coloured.

Is The reverse reaction of photo synthesis is called what?
metabolism - photosynthesis is the process of building food ( read amino acids) from simple molecules by capturing energy where as metabolism is the process by which cells break down these amino acids to extract the energy.
What is photo-oxidation in plants?
Oxidation is a process in which something (an atom or molecule or substance) loses an electron to something else. Photo-oxidation is therefore the process of oxidation which is caused by shining light on it. Often, light can be used to cause reactions to happen, such as oxidation. The term "photo" comes from "photon" which is light.
What is photo chemical reaction?
chemical reaction brought on by light ( latin: photo - light)
What evidence of a chemical reaction is shown in the photo?
lol what photo
What is the photo-chemical reaction that takes place in the presence of sunlight and is responsible for providing food for everyone?
The photo-chemical reaction that takes place in the presence of sunlight and is the source of food for everyone is called photosynthesis.
How do we see green light?
The process of seeing green light is a photo-chemical reaction in the rods and cones of your retina.
What is law of quantum energy and quantum mass?
In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.
What is another name for light dependent reations of photosynthesis?
The exergonic reaction is a chemical reaction that releases energy (photosynthesis). The product of light dependant reactions is called endergonic reaction. It is a chemical reaction that requires energy.
What is the definition of photo-chemical?
Related to or caused by the chemical action of light
What has the author H Stanley Allen written?
H. Stanley Allen has written: 'Photo-electricity' -- subject(s): Photoelectricity, Electrons 'The quantum and its interpretation' -- subject(s): Quantum theory, Atoms
Define photography from the original Greek?
photography photo-graphy (φωτογραφία) photo (φώς) :light graphy (γράφημα) : drawing a drawing made from light
What is relation of co2 to the photo chemical reaction?
photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules' absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules. These new chemical species can fall apart, change to new structures, combine with each other or other molecules, or transfer electrons, hydrogen atoms, protons, or their electronic excitation energy to other molecules. Excited states are stronger acids and stronger reductants than the original ground states.
How can photochemical smog be controlled?
if we control the primary precursors of photo chemical smog,such as NO2 and hydrocarbons,the secondary precursors such as ozone and PAN,the photo chemical smog will automatically be reduced.
