The Bohr model for the hydrogen atom posits that the atom's electron can only occupy circular orbits, with the circumference of each orbit containing an integral number of de Broglie wavelengths.
Suppose that an electron in a particular hydrogen atom is in the first excited orbit, corresponding to
n = 2.
(a)
What is the radius (in nm) of this electron's orbit around the atom's nucleus (a proton)?
nm
(b)
What is the de Broglie wavelength (in nm) for an electron in this orbit?
nm
An atom (not a hydrogen atom) absorbs a photon whose associated wavelength is 375 nm and then immediately emits a photon whose associated wavelength is 580 nm. How much net energy is absorbed by the atom in this process?
Calculate the velocities of electrons with de Broglie wavelengths of 1.7×103 nm and 5.0 nm, respectively.
