To explain: The reason why neon do not absorb orange and red wavelength.

Answer to Problem 1CQ
The reason why neon do not absorb orange and red wavelength is explained.
Explanation of Solution
Emission spectrum of the elements shows colors due to the electrons excited by electrical discharge which jumps from one state to the other. In case of neon, the reddish-orange discharge is due to the transitions excited from 3p states to the lower energy. The density of the electrons in the ground state of absorption spectrum is less. Therefore, there is no noticeable absorption in these states.
So, the population of electrons in ground state of neon atom is less which results in lowered absorption of the red-orange light with a reason having lack of electrons. The remaining wavelengths are absorbed by the ground state neon atoms having energy greater than 16 eV. Accordingly, the absorbed wavelengths will be less than 100 mm.
So, because of less density of atoms in the 3s state of neon, the absorption of red-orange light is minimal.
Conclusion:
Hence, the reason why neon do not absorb orange and red wavelength is explained.
