reactants are material particles having a specific mass which is converted into products and their mass is conserved while light has no specific mass and not present in products as a component. the light may catalysed a reaction.
I am not sure if this is a reactant but I know that if it isnt then the process it takes to get it has a reactant in it. ATP and NADPH. These are synthesized by the use of light energy which occur in the thylakoid membranes of the chloroplasts. I hope this helps.
Light is not a reactant or a product in a chemical reaction because it does not undergo a chemical change. While light can provide the energy needed to drive certain reactions (such as photosynthesis), it is not consumed or produced in the process.

Oxygen is both a reactant and a product of photosynthesis. It is produced as a product when water is split during the light reactions, and it is also consumed as a reactant in the electron transport chain of photosynthesis.
You can predict the reactant in a decomposition reaction by looking at the products formed and reversing the process. Typically, the reactant will be a single compound that breaks down into two or more simpler substances. The reactant is often a stable compound that can be decomposed under specific conditions, such as heat or light.

A combustion reaction typically involves a reactant containing carbon and produces heat and light as it reacts with oxygen in the air to form carbon dioxide and water vapor.
The Limiting Reactant is the reactant that runs out first in a reaction.
