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 made up of tiny particles called âcorpusclesâ having negligible mass. 1  These particles (corpuscles) are perfectly elastic. 2  The corpuscles are emitted from the luminous sources such as Sun, candle, electric lamp etc. 3  The tiny particles (corpuscles) always travel in a straight line in all directions.
