Fig. 10.2 shows examples of a continuous, an emission and an absorption spectrum. Emission Spectra The discrete bright (dark) lines in the emission (absorption) spectrum can be explained by treating light as a photon that is emitted (absorbed) by an atom, as shown in Fig. 10.3. (For this lab we are going to concentrate on emission spectra.)

The result is called a line emission spectrum, and can serve as a 'fingerprint' of the element to which the atoms belong. For example, the line spectra shown below for the elements helium and carbon are clearly quite different (colors can be seen in the PDF document on-line).
Color As A Clue in Metal Identification Methods. A strong clue in metal identification is color. It can differentiate precious metals, magnesium, aluminum, brass, and copper. If there are signs of oxidation, remove it via scraping to reveal the color of the unoxidized surface. Scraping aids in the identification of copper, magnesium, and lead.
Session Description: The term hepatobiliary injury encompasses a wide spectrum of diseases of the liver and biliary system, which can be caused by viral infections, alcohol, xenobiotic compounds, metabolic disorders, neoplasia, and autoimmune disorders, among others. Unfortunately, in many of these diseases, treatment is limited; thus, there is ...

Virtual reality (VR) is becoming an increasingly important way to investigate sensory processing. The converse is also true: in order to build good VR technologies, one needs an intimate understanding of how our brain processes sensory information. One of the key advantages of studying perception with VR is that it allows an experimenter to probe perceptual processing in a more naturalistic ... -Weeaboo senzawa

IDENTIFICATION AND USE: Difluoromethane (HFC32) is a colorless gas. It is used in refrigeration, organic synthesis, and as a tracer gas in gas chromatography and photoacoustic spectroscopy. HUMAN EXPOSURE AND TOXICITY: There are no data available. ANIMAL STUDIES: Inhalation of HFC32 (up to 50,000 ppm) caused no organ-specific effects.
