In the space below list possible elements that might match the lines you have recorded (you should find at least one, but there may be several possibilities depending on your unknown). 1. Use the following table to compare wavelengths for your unknown and the potential elements you think it could be. Line Color Recorded wavelength of unknown element Corresponding wavelength for Possible Element #1 Corresponding wavelength for Possible element #2 Corresponding wavelength for Possible element #3 Part III: Unknown element Record all the lines possible and use the spectral charts to try to identify the element. Remember to use the calibration information from Part I of the lab to increase the accuracy of your observations. Figure 4: Unknown gas discharge tube 5
