An excited hydrogen atom is capable of emitting radiation of
A)a single frequency.
B)3 frequencies.
C)many more than 3 frequencies.

Question

Quizplus · Accepted Answer

An excited hydrogen atom can emit radiation in the form of photons when an electron in a higher energy level drops to a lower energy level. The energy difference between the two levels determines the frequency of the emitted photon according to the equation E=hf (where E is energy, h is Planck's constant, and f is frequency). Hydrogen atoms have multiple energy levels, so when an electron drops from a higher level to a lower one, it can emit photons of different frequencies. Therefore, a single excited hydrogen atom is capable of emitting light with many more than three frequencies.
