Interactive hydrogen atom with Bohr orbits (n=1 through n=6). The electron sits in n=1 (ground state) by default. Students can click higher orbits to 'excite' the electron to that level. When the electron drops to a lower level, it emits a photon shown as a colored flash - calculate wavelength using
