Hypothesis/Purpose : The purpose of this lab was to understand how each element has a different monochromatic color which defines the element.
Background Information : Scientists have used spectroscopes for a long time. Scientists found several other planets this way that orbited stars such as 51-Pegasus. Emission lines are specific chemicals give off radiation at certain colors once electrically charged or heated. Absorption lines, when a hot star passes through a colder gas, are seen because the central part is cooler than the star's atmosphere. The first planet discovered outside our solar system was in 1991. You can determine which direction an object is moving by the length of it's waveform. This is known…show more content… This would display other monochromatic colors. If we wrote down the monochromatic colors, then we would not be able to define the unknown spectroscopes as every element has it's own monochromatic color, however, we would be able to narrow our search down by the element's polychromatic color.
Conclusion : During this lab, I learned that each element has it's own distinct monochromatic color. Their polychromatic color may be similar to other elements'. A monochromatic color is a variation of several colors. Polychromatic colors are all the tints, tones, and shades of a single hue. However, by looking at the polychromatic color, we may be able to narrow down the selection of an unknown. To read a monochromatic color, you list the colors from left to right with approximate spacing. To find an unknown, you would put the unknown's monochromatic color under several other possible elements and pick out the parts from other spectroscopes that overlap. The one the overlaps fully is the unknown element. I also learned that every light contains a spectroscope, whether it be a lamp, looking out the window, or a phone because all these objects emit light. Scientists are also able to determine the star's age with spectroscopy because the amounts of matter made up of other elements than the normal hydrogen and
