This mechanism could account for the well-known asymmetries. See the article on laser lines for many more lines generated with lasers. Emission spectra are produced by passing electrical or thermal energy through gases in which the atoms do not experience many collisions (because of the low. The same line shape should also occur for the discrete line spectra of X-rays emitted from metals. The wavelengths of the lines are characteristic of. It was based on understanding the SHARP LINE. atoms is known as a line spectrum, because the radiation (light) emitted consists of a series of sharp lines.

In Paragraph Completion, learners complete a paragraph by selecting from a short list of terms which fill in the blanks. Bohr s greatest contribution to science was in building a simple model of the atom. The Concept Builder has three activities - Paragraph Completion, Line Identification, and Match That Color.

Table 1: Table of spectral lines which are frequently used in optics. The Line Spectra Concept Builder targets a learner's understanding of line spectra. The refractive indices of optical materials (mostly optical glasses) are often specified at a number of standard wavelengths, in particularly at the lines C, C', D, d, e, F and F' (see Table 1). For these orbits, the angular momentum is integral multiple of. Overview of Line Spectra An atom has a nucleus in its centre and electrons revolve around the nucleus in designated orbits. There are also laser lines which can fulfill similar purposes. Line spectra is the spectrum of discrete wavelengths emitted or absorbed during transition by an electron.
