During the light reactions of photosynthesis, hundreds to thousands of photons may be absorbed by a single chlorophyll molecule in the reaction center of a photosystem. These photons provide the energy needed to drive the electron transport chain and convert light energy into chemical energy in the form of ATP and NADPH.
Photons are tiny particles of light that carry electromagnetic energy. They are the basic unit of light and are responsible for its properties, such as intensity and color. Photons are emitted and absorbed by atoms and molecules, creating the phenomenon of light.
Photons are particles of light that carry energy. When light is absorbed by a material, photons transfer their energy to the material's atoms, causing them to become excited. This excitation can lead to the emission of light when the atoms return to their original state, releasing photons in the process.
In a photosystem, an enzyme, known as the reaction center, is surrounded by proteins that enhance the absorption of light and transfer energy to it. The reaction center absorbs the light, which is comprised of photons, and then transfers the energy to one of two types of terminal electron acceptors.
Photons are particles of light that have properties such as energy, momentum, and polarization. They influence the behavior of light by determining its intensity, color, and direction. Photons can be absorbed, reflected, or transmitted by materials, leading to phenomena like reflection, refraction, and diffraction.
Photons are elementary particles that have properties of both particles and waves. They have no mass, travel at the speed of light, and carry electromagnetic radiation. Photons can be absorbed or emitted by atoms, leading to phenomena like the photoelectric effect and the creation of light.
Quantum yield of a photochemical reaction refers to the efficiency with which a light-induced process, such as the generation of a particular product or the initiation of a reaction, occurs. It is defined as the number of moles of a product formed per mole of photons absorbed by the system. A high quantum yield indicates that a higher proportion of the absorbed photons lead to the desired outcome.

A substance such as quinine glows because when absorbed light photons release photons of another wavelength. When the absorbed photons are in the ultraviolet range and the triggered emission is in the visible spectrum, a substance will glow under black light.

Photons are absorbed by chlorophyll molecules in chloroplasts during photosynthesis. This absorption of light energy is used to drive the process of converting carbon dioxide and water into glucose and oxygen.
The light absorbed by chlorophyll initiates the light reactions of photosynthesis. Chlorophyll molecules in the thylakoid membranes of chloroplasts absorb light energy and convert it into chemical energy, which is used to drive the conversion of water and carbon dioxide into oxygen and carbohydrates during photosynthesis.

During photosynthesis substances such as carbon dioxide and water are used to produce sugars such as glucose. Photosynthesis, as the name implies, uses light from the sun (photons) in order to make this reaction happen. First, the photons reach the thylakoid membranes which are located in the chloroplasts. This is where the light dependent reaction happens. The energy from the photons allows the start of the electron transport chain in which NAPD is reduced into NADPH. This creates a proton gradient which 'powers' ATP synthase so it can produce ATP molecules. Also it is during the light dependent reaction that oxygen is released into the atmosphere. Then, you have the light independent reaction. During this time, a series of reactions convert carbon into glucose.
Light energy is transferred into an object when photons from the light source are absorbed by the object's surface. The absorbed photons increase the kinetic energy of the object's molecules, causing them to vibrate and generate heat, which is thermal energy.
Depends on the mixture. There are two different reactions when atoms bond: exothermic and endothermic. During an exothermic reaction, energy is given off in the form of heat or light. In a endothermic reaction, energy is absorbed.

Light travels in the form of waves or particles called photons. It stops only when absorbed by matter.
