How can it be independent of the atom. It needs the
atom to produce the photon to produce the electromagnetic
wave. You said the higher is the frequency of the wave,
the more enegy must the photon have. Since the photons
came from the electron in the orbitals. How come the
atoms can't produce high energy electrons or high
frequency wave (or photon). Isn't it the frequency of the
photon is the difference between certain energy levels of
the electrons? In Iron for example. Know what is the frequency
of the higher level of the atom and the lowest level. Can't the
difference be equal to ultraviolet but only topping in the
blue.

When iron produce red light. Which of the 2 orbital
differences produced red. But you said other colors
are also produced. How come it peak at red.
