Emission Spectra of Light Sources The purpose of this la

The purpose of this lab was to look at the emission spectra of various light sources: incandescent, fluorescent and neon lights, and reflected sunlight. Diffraction glasses were used as a simple version of a spectroscope for this home experiment. When viewing the spectra of incandescent and fluorescent lights, all other light sources were eliminated. The light sources were viewed using only one eye, making sure the light source could enter the slit in the end of the spectroscope, with the spectra reflected to the side with the Angstrom measurements. Colored pencils were used to draw what was seen in the spectroscope, and the Angstrom measurements were included in the drawing, along with the relative width of each band of color in the spectrum. The relative intensities of each color band were also noted.

red, orange, yellow, green, blue, purple

1. The largest spectrum range and brightest colors were seen

when observing reflected sunlight. The next broadest and brightest spectrum was seen with the incandescent light, but the yellow light was not visible. The fluorescent light gave the same breadth of spectrum as incandescent light, but the intensities were much smaller. With the neon light, ???? CANNOT READ YOUR FAX

2. Bohr's atomic model was based on the fact that when matter is heated, it gives off light (Carpi, 2005). Bohr knew that when pure elements were excited by electricity or heat, they gave off distinct colors. For instance, when an electric current is passed through a tube containing neon ga
