CalculationsSpectroscope Calibration:Spectroscope calibration graph (Hand Drawn)After you have identified your lines,create a hand-drawn plot on a piece of graph paper of the wavelengths (from Table 1) onthe ordinate (y-axis) versus scale divisions that you recorded in lab on the abscissa (x-axis). Use a straight-edge to draw a line through the points on the graph.If this line doesnot approximate the points on the graph correctly, adjust the wavelength assignmentsmade above.For example, you may have assigned a wavelength of 7065 Å to yourobserved red line. However, the observed red line may actually be the line at 6678 Å.You may adjust your assignments of wavelength in order to correct your graph.
