1. Description of the emission spectrum of the hydrogen gas tube Color of Hydrogen discharge tube emission: Scale Reading Wavelength, nm Post-lab Although color and wavelength are the experimental results that we record when looking through the spectroscope, energy is the important quantity in relating the spectrum to the energy levels of atoms. Calculate the energy of the red-orange hydrogen atom spectral line (See data table for the hydrogen spectra). Show the set-up for each step below. a. Calculate the wavelength in m: b. Calculate the frequency in Hz: c. Calculate the energy in Joules of a photon of the emission. d. Repeat the calculations (a through c) for the violet line. e. Calculate the energy for the blue (486 nm) and indigo (434 nm) lines in Joules
