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.
Matter is that substance that can occupies space and has mass. For example gas,liquid etc. are mass like my friends said. But photons which are fundamental particles of light occupies space but dont have mass,meaning they are not matter. Hope this helps.
