Why physical operators are Hermitian operators in quantum mechanics?

A) If an element has an emission spectrum with bright lines at 400nm and 800nm, where would you expect to see dark lines in the element’s absorption spectrum?

B) Use the Bohr model of the atom to explain why an emission spectrum is a few separate lines, rather than a continuous pattern.

If the energy levels in the neon atom are 4.3 x 10 -18 J and 3.97 x 10 -18 J and 1.07 x 10 -18 J Use the data to calculate two photon frequencies that could be absorbed by neon in the lowest state
