Problem 2: The goal want to convert our distance dimension units from pixel to wavelength. To calibrate the wavelength readings (x-axis) by matching the peaks of the spectra to literature data. To calibrate the wavelength readings (x-axis), use linear regression to convert the pixel count to true wavelength ($nm$).
