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.
Best Answer: Light has properties of both particles and waves. When we think of light as a particle, we call that particle a photon. Photons do not have mass, but they can carry momentum. That's because photons have energy. Mass and energy are two sides of the same coin; in fact, you might say that mass is tightly-compacted energy.
