Let's say we are using a spectrometer to observe the order spectrum of mercury, a polychromatic source.
Each order contains a an array of colour bands.
In the case of the following image: http://imgur.com/a/bnm9r , I was wondering if each Fraunhofer envelope represented one order, (m = 1 , 2 , 3 ...) or if each line under the envelopes represent each order, where the central line in the first envelope is the central maxima.
Also, the following picture is the order spectrum of hydrogen http://imgur.com/a/DkrJC
Why is it that after each order, the spectral lines separate further away from each other?
