The de-Broglie wavelength of an electron in the first Bohr orbit is
equal to half the circumference of the first orbit
equal to one fourth the circumference of the first orbit
equal to the circumference of the first orbit
equal to twice the circumference of the first orbit
Whenever a hydrogen atom emits a photon in the Balmer series, it
may emit another photon in the Paschen series
need not emit any more photon
may emit another photon in the Balmer series
must emit another photon in the Lyman series
