1. Using the values from the helium emission spectrum, generate a calibration curve on Microsoft Excel or other graphing software. If you are new to Microsoft Excel, specific instructions (with pictures) are given at the end of this lab and will be discussed in lab. a) In Excel, create a column labeled "scale position." This will serve as your x-values. Create another column labeled "wavelength." This will serve as your y-values. b) Enter the values for your scale position and wavelengths into each column. Do not put unit labels with the numbers. c) Create four separate graphs, one each for the four required types of trendlines ("linear", "logarithmic", "exponential", and "polynomial"). Each graph will have the same data plotted but have a different trendline. See the "Curve Fitting Using an Excel Spreadsheet" section at the end of this write-up for additional information about how to make these graphs. i. ALL graphs must conform to the requirements discussed in lab. 1) graph must take…
