Vedclass · Answer

(C) neon sign tube is filled with neon gas,which is subjected to a high voltage,causing the electrons to become excited. When these electrons return to the ground state,they release energy in the form of packets,known as photons,which causes the glow.In neon gas,atoms exist in a specific pattern,which leads to the formation of a line spectrum rather than a continuous spectrum.Since these electrons emit photons when transitioning from an excited state back to the ground state,they produce an emission spectrum. The atoms in the neon gas are excited by the high voltage and do not absorb energy from an external source to produce a spectrum. Therefore,a neon sign does not produce an absorption spectrum.
