The longest wavelength in the Lyman series is 121.5 nm. Use this wavelength together with the values of c and h to find the ionization energy of hydrogen.
How much energy is required to remove an electron in the n=2 state from a hydrogen atom?
Find the wavelength of the spectral line that corresponds to a transition in hydrogen from the n = 6 state to the n = 3 state. In what part of the spectrum is this?
How many different wavelengths would appear in the spectrum of hydrogen atoms initially in the n=5 state?
A beam of 13.0-eV electrons is used to bombard gaseous hydrogen. What series of wavelengths will be emitted?
When radiation with a continuous spectrum is passed through a volume of hydrogen gas whose atoms are all in the ground state, which spectral series will be present in the resulting absorption spectrum?
Suppose a proton and an electron were held together in a hydrogen atom by gravitational forces only. Find the formula for the energy levels of such an atom, the radius of its ground-state Bohr orbit, and its ionization energy in eV.
What is the shortest wavelength present in the Paschen series of
spectral lines?
Find the frequency of revolution of the electron in the classical model of the hydrogen atom. In what region of the spectrum are electromagnetic waves of this frequency?
A certain ruby laser emits 1.00-J pulses of light whose wavelength is 694 nm. What is the minimum number of Cr³+ ions in the ruby?
