1 3. Later this semester you will learn about electronic transitions within an atom's electron cloud.For this exercise, make a graph of the known spectral lines found for a Hellum nucleus(independent variable) versus the experimental values found using a spectroscope in the lab(dependent variable).Known Wavelengths of Helium (nm)Spectroscope Reading388,95.3468.65.7501.66.1587.66.8667.87.7706.58.3a. Make a graph of this data. Note: The trendline in this case is not linear, but ratherexponential!i. Forecast the trendline forward and backward (as appropriate) to answer thefollowing questions. To do this, after printing the graph use a ruler to drawvertical lines corresponding to each question below.1. What is the actual wavelength of the spectral line (in nm) for a spectralreading of 6.5?2. What is the actual wavelength of the spectral line (in nm) for a spectralreading of 4.6?3. What is the actual wavelength of the spectral line (in nm) for a spectralreading of 8.5?
