Using the spectrometer, observe light from each of these sources, check the correct type of spectrum you observe in the table below. Remember that many overlapping line spectra can be seen as a continuous spectrum, thus looking like a blackbody.

1. During the daytime hours point your spectrometer towards the sky, but not directly towards the sun as it could damage your eye. It does not matter if it is a cloudy day, you will observe the same spectrum on both sunny and cloudy days. Take a photo of you doing this.
2. With all other sources of light removed, point your spectrometer at a fluorescent light. Fluorescent lights are the long tube lights used mainly in office buildings. Alternatively, if you have a compact fluorescent light bulb this will work too. Take a photo of you doing this.
3. With all other sources of light removed, point your spectrometer at an incandescent light. Incandescent lights are the traditional light bulbs in household lamps. Take a photo of you doing this.
4. With all other sources of light removed (night time if possible), point your spectrometer at an automobile headlight. Take a photo of you doing this.
5. With all other sources of light removed, point your spectrometer at a neon light. You may need to go to a store with a lit "open" light or something similar.
6. With all other sources of light removed, point your spectrometer at a street light.
7. Fill in the table below with your results. Include a photo of this table in your lab submission.

Computer Monitor Spectra

With all other sources of light removed, point your spectrometer at each of the sources below and check the correct type of spectrum you observe in the table below. Take a photo of you doing this for each color.

Part 3

Spectral Temperature

1. Point your spectrometer towards the sky and qualitatively determine the wavelength of the brightest light.
2. Point your spectrometer towards an incandescent light and qualitatively determine the wavelength of the brightest light.
3. Point your spectrometer towards an electric stove top that's glowing red and qualitatively determine the wavelength of the brightest light. (You can use a blue flame if you have a gas stove.)
4. Record the wavelength read with the spectrometer in the table below. If you can, take a photo of the inside of the spectrometer with the reading on the scale.
