The Atomic Spectrum

  1. When doing an experiment in order to observe the atomic spectra of some gas. We observe while peaking through the diffraction grating, symmetrical lines starting from n=1. Where does this symmetry arise from? Why do we see the same spectrum repeated on both, left side and right side. As if there was a mirror instead of the gas tube that reflected the first spectrum to the opposite side.

    Thanks.

    The setup is symmetric, there is no reason why the lines should be asymmetric.
