Two color coding schemes exist to guide applicators when selecting. nozzles for pesticide applications. The color schemes are designed to. help applicators achieve accurate, effective crop protection. It may be. confusing, but the color schemes represent flow rate and droplet. size and are independent of one another.
If E = mc^2, and light = E, then light = mc^2. Therefore light is matter. Given, as Claude Bile stated (post #4), âE = mc^2 is the equivalence of mass and energy, not matter and energyâ, I guess they are saying that because light has relativistic mass it is matter.
Light is composed of electric and magnetic fields and thus its alternate name electromagnetic spectrum. Light can be absorbed and emitted by atoms and molecules. The precise details of which give us the world we see around us. Chemists are interested in the details of absorption and emission of light by matter because these details can be viewed as fingerprints of atoms and molecules as well as their chemical properties.
