Atomic Spectra Lab Report

The purpose of this spectroscopy, atomic spectra, and light lab was to further your understanding of how different gases are given specific wavelengths based on the variety of color that their light gives off. (Grossie, 285). Every ion gives off a different light configuration based on the amount of energy they hold. (Grossie, 285). A spectroscope is used to break down the light given off by the gas into different colored lines in different areas on the scope. The measure of these lines is what is referred to as the wavelength. Recognizing the similarities and differences between ions was also taught in this lab. Throughout the lab, various amounts of data were collected. Four different gases were observed and the data is provided in the tables and plots on the last few pages. Table 1 and Figure 1 both hold …show more content…
This was when there were a series of different light bulbs that had to be observed on, off, and though a diffraction grating. (Sanders, 2). The other part of this section that was not described in Table 5 was the part with the array of LED lights. The observations were made through a diffraction grating as well and the light that was visible was in a continuous fashion.  Let’s start with discussing the difference between experimental and calculated values of the wavelengths. In just about every table there is a column for each of those categories. So what exactly is the difference? The difference is that the experimental value is the wavelength that had been provided ahead of time, usually in a chart. This wavelength is based on observations only. Calculated wavelengths on the other hand, are values that were computed by a specific formula. Both of these values share the same uncertainty because you cannot be 100% exact for either value. By looking at the data tables and figures provided, you should be able to notice that the two values are extremely close to each other. This should
