Day 134: Spectrum of Hydrogen

Today, students started to explore the Bohr model of the hydrogen atom by analyzing the hydrogen spectra. They used a couple of pins and polar graph paper to sight the angle of each spectral line. They then calculated the wavelength and energy of each line. I provided them with the energy levels of the hydrogen atoms without stating the source to see if they could identify the pattern. While most groups accurately measured the spectra, they didn’t immediately connect the energy of the line to the transition between energy levels. We’ll discuss this more tomorrow.
