Question
Identify the wavelengths of the Neon lines in Figure 3 as many as possible using the information in Figure 4 and 5. Some nearby lines
Identify the wavelengths of the Neon lines in Figure 3 as many as possible using the information in Figure 4 and 5. Some nearby lines may overlap. 2. Determine the centroids (i.e., pixel positions) of the lines. (There could be many different ways to do it.) 3. Obtain a linear least square fitting between the pixel positions of the Neon lines that you identified and their wavelengths. How good is the fitting? The linear fitting is the wavelength solution. 4. Apply the wavelength solution that you obtained in step 3 above to your blackbody spectrum. Now you know the wavelengths of the blackbody spectrum. What is the temperature of your blackbody?
