Which of the following best explains how Bohr’s postulate of stationary states resolves the classical radiation problem for the hydrogen atom?
(a) The electron’s wave function forms a standing wave that destructively interferes with its own electromagnetic radiation, so no energy is emitted in the allowed orbits.
(b) Electrons are allowed only in specific energy levels where they do not radiate despite being accelerated, preventing energy loss.
(c) Because the electron’s angular momentum is quantized, it experiences no net acceleration in the allowed orbits, so radiation is impossible.
(d) Any radiation emitted by an electron in an allowed orbit is instantly re-absorbed by the atom, resulting in no net energy loss.
