Alpha and beta-minus radiation explained for as level physics.
Using the 24" Boller & Chivens telescope (University of Colorado at Boulder) with its attached spectrograph and corresponding CCD camera, spectra of several stars were observed and recorded for analysis. The analysis focuses on the three stars: Betelgeuse, Procyon, and Rigel.
Air is equally important as much as water is for our survival. However, this is the least regarded entity as it is consistently taken for granted, and taken for a ride (I do not just mean the airplanes and choppers!) Here are a few ways to appreciate the clean air that we need for healthy breathing.
The yellow, green, red, and blue sparklers were found to be composed of the chemical compounds NaCl, BaCl2, SrCl2, and CuCl2 respectively. Using emission spectroscopy we recorded the known emission values of each of the known chemicals, then recorded the emission values of the sparklers. We then determined the best matching data for each sparkler and known substance.
