Document Summary
An electric current passes through a neon tube and gives energy to the neon gas. Thus, the electron in the neon gas gives off their energy and drops to lower energy levels, which produces emission line. Using the video source below, and the video atoms and starlight (#3645 in library), answer the following questions. Questions: what physical quantities can be derived from the science of spectroscopy, give an example of an object that produces a continuous spectrum. An iron bar heated to a very high temperature to the point of glowing. Cold gas is in between an observer and a continuous source. The cold gas absorbs all the energy required to boost its electrons to its various energy levels and lets all other light passes through. The surface is cooler and thinner, than the gas underneath. Speed of atoms----- the faster the atoms moved the hotter the object and vice versa. Kelvin is proportional to the movement of atoms.
