1. Using the values from the helium emission spectrum, generate a calibration curve on Microsoft Excelor other graphing software. If you are new to Microsoft Excel, specific instructions (with pictures) aregiven 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. Createanother 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 unitlabels 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 plottedbut have a different trendline. See the "Curve Fitting Using an Excel Spreadsheet" section atthe 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 up the entire page2)data must take up the entire graph3)chart must have a descriptive title4) x-axis and y-axis must have appropriate titles (with units)5) each graph must have one of the four assigned trendlines6) equation for the trendline must be shown on graph7) R² value must be shown on graph.52. Using the scale position reading for the hydrogen spectrum and the equation generated from yourcalibration curve, calculate the wavelengths (in Å) for each of the four lines in the hydrogenspectrum. Compare these calculated values with the reported values. Look up the four lines that arevisible in the atomic spectrum of hydrogen (Be sure to provide a reference or URL).3. Convert the wavelengths in Å to nm and m, and then calculate the frequency in hertz for eachobserved hydrogen emission line from your graph.4. Use equation 5, the Rydberg equation, to calculate the value of nu for the electron transition thatcauses each line in the Balmer series.5. Calculate the energy (in kilojoules) of one mole of photons for each line.6. Compare the values you obtained for the wavelengths of the first four lines in the Balmer series to thevalues you looked up in the reference. Calculate the percent error. (Typical errors are less than 5%).
