Of the various wavelengths emitted from a hydrogen gas discharge tube,those that are associated with transitions from higher levels down to the n = 1 level produce which of the following?
A)infrared
B)visible
C)mixture of infrared and visible
D)ultraviolet

Question

Quizplus · Accepted Answer

When an electron in a hydrogen atom goes from a higher energy level to the ground state (n=1), it releases energy in the form of a photon. These photons have specific wavelengths that correspond to specific energy differences between the levels. The transitions from higher levels to n=1 result in the emission of ultraviolet photons.
