A hydrogen atom (Z = 1) is in the fourth excited state, and a photon is either emitted or absorbed. Concepts: (i) What is the quantum number of the fourth excited state? 12 345 (ii) When an atom emits a photon, is the final quantum number nf of the atom greater than or less than the initial quantum number ni? greater thanless than (iii) When an atom absorbs a photon, is the final quantum number nf of the atom greater than...

Suppose a photon is absorbed by the electron in a hydrogen atom in an n= 2...

Suppose a photon is absorbed by the electron in a hydrogen atom in an n= 2 state. What wavelength should the photon have to enable the electron to transition to the n= 4 state? Once the photon is absorbed, what are the various wavelengths of photons that could be emitted by the atom? (Use Bohr approximation).

a. A relatively rare transition of the hydrogen atom emits a radio photon with with ?...

a. A relatively rare transition of the hydrogen atom emits a radio photon with with ? = 21 cm. This emission line is extremely important to astronomers for two main reasons: it cuts through most gas and dust without being absorbed and, although transition is rare, there is so much hydrogen in space that the 21 cm photons are themselves quite common. Suppose that one such photon from a distant galaxy is measured to have a wavelength of just 11...
