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.
1 Electrical-Electrical energy is generated by the movement of electrons. 2  Gravitational-Large objects such as the Earth and the Sun create gravity and gravitational energy. 3  Heat-Heat energy is also called thermal energy. 4  It comes from molecules of different temperatures interacting. 5  Light-Light is called radiant energy.
