Electrons in a certain energy level n=n1, can emit 3 spectral lines. When they are in another energy level n=n2. They can emit 6 spectral lines. The orbital speeds of the electrons in the two orbits are in the ratio can emit 3 spectral lines. When they are in another energy level n=n2. They can [...]
