All matter, whether a solid, a liquid or a gas, is composed of atoms. Atoms consist of a nucleus, made up of protons neutrons and a cloud of electrons that circle the nucleus in orbits defined by their various energy levels. Although the power of a laser beamdepends on the energy levels of these electrons in the … See more Light is an electromagnetic wave, meaning that it has both an electric component and a magnetic component. For this discussion, we can ignore the magnetic part and just focus on the electric portion. This wave is much … See more When light encounters a boundary between two different media – such as air and glass, for example – some of it is refracted, or transmitted through the glass, while the rest is reflected.
