Absorption spectrum examples
Types of Spectrum-Emission and Absorption Spectrum-Fraunhofer ...
An absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum. Hydrogen Emission and Absorption Series. The ...

The absorption spectrum of a certain red dye is shown above. If a student analyzing the same concentration of this dye neglected to wipe fingerprints off the cuvette before placing it in the spectrophotometer, how would the absorption curve be affected? ... Examples and equations may be included in your answers where appropriate. Question 1 ...

Spectra can be simplified to one of three basic types. Simple examples in the visible wavebands are shown below: Type of Spectrum Photographic example Continuous (or continuum) Absorption (dark line) Emission (bright line) One means by which a continuous spectrum can be produced is by thermal emission from a black body.
