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 a form of electromagnetic radiation. Visible light is a narrow range of wavelengths of the electromagnetic spectrum. By measuring the wavelength or frequency of light coming from objects in the universe, we can learn something about their nature. Since we are not able to travel to a star or take samples from a galaxy, we must depend on electromagnetic radiation to carry information to us from distant objects in space. The human eye is sensitive to a very small range of wavelengths called visible light.
