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.
Then waves with higher frequency are called X-rays and still higher are gamma rays - these have the peaks closest together. Sometimes you'll hear that light is made of photons. What that means is that when light is absorbed or emitted, the energy in the wave comes in lumps. The size of those lumps (or quanta) of energy depends on the frequency. The higher the frequency the more energy per photon. -Tamara(w.
