Unusual breath odors are common in kids. Typically there isnât anything to worry about, but there are some breath odors that indicate an underlying problem. In children smelly breath that persists throughout the day is most often the result of mouth-breathing, which dries out the mouth and allows the bacteria to grow.
Light is composed of particles called photons, and matter is composed of particles called electrons, protons, neutrons. It's only when the mass of a particle gets small enough that its wavelike properties show up. To help understand all this let's look at how light behaves as a wave and as a particle.
Light is electromagnetic (EM) radiation, the fluctuations of electric and magnetic fields in nature. More simply, light is energy and the phenomenon of color is a product of the interaction of energy and matter. As a reasonable starting place for discussing color, we need to take a brief look at the physics of light and the particular nature of light sources. Light has the properties of both particles and waves.
