Document Summary

Any change in the amount of energy stored results in a spectral line. Spectroscopy: the study of the behavior of em radiation when it interacts with matter. Spectral lines: interaction of em radiation with matter. Isaac newton at his woolsthorpe manor home. 1666: white light prism roygb)v - continuous spectrum. White light filter b prism b - spectral line. They are (cid:498)fingerprints(cid:499) that uniquely identify compounds of molecules and atomic. Ex: for a specific atomic element its emission line pattern is exactly that of its absorption line pattern elements. A hot solid, liquid, or highly compressed gas emits a continuous spectrum. A hot, low density gas emits a bright emission line spectrum. The line wavelength pattern depends on the specific elements present in the. A continuous spectrum passing through a foreground cooler gas produces a. The line wavelength pattern depends on the specific elements present in the spectrum fraunhofer lines. Found helium dark lined absorption line spectrum.
