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.
When light interacts with matter, it behaves as discrete packets of energy (quanta) called photons. The energy of a photon, Ïµ, is proportional to the frequency of the light wave: Ïµ = hÎ³, where h is Planckâs constant (1.58 Ã 10â34 calÂ·s, or 6.63 Ã 10â34 JÂ·s), and Î³ is the frequency of the light wave. It is customary in biology to refer to the wavelength of the light wave, Î», rather than to its frequency, Î³.
