Purpose: There were multiple purposes in this experiment. The first was to view and record the emission spectra of fluorescent light, incandescent light, and a helium light using a spectrometer. The second required the creation of a procedure to determine the composition of a solution composed of two ionic salts. Using a spectrometer, different ionic salt solution’s emission spectrum were observed and compared to the unknown salt’s emission spectrum in order to determine its composition. The final objective was to construct a partial energy level diagram of hydrogen after observing its emission spectrum. Procedure: For the first part of the lab, a spectrometer was used to measure the emission spectrum from various sources of light. For fluorescent light and the helium light, distinct line spectrums were given off. This means that distinct peaks were observed using the computer program software. For the incandescent light a continuous spectrum was observed using the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
