What is a spectrum? 2. ls white light a simple color or misture of a number of colors? All emission spectra are characteristic of the particular elements. That is, they are like fingerprints, each unique to each element. If you found these lines in the spectrum of a certain substance, what would this indicate? 3. 4. Does the incandescent bulb produce a continuous, emission line or absorption linde spectrum? Describe which of the three kinds of spectra (continuous, emission line, absorption line) you observe in the fluorescent bulb. What element is present in the fluorescent lamp which produces the line spectra component on the observed spectrum? 5.
