If the electron in a hydrogen atom is to make a transition from the first excited state to the fourth excited state, what frequency of photon is needed? What type of light is this?
Answer to relevant Questions(a) How many transitions in a hydrogen atom result in the absorption of red light: (1) one, (2) two, (3) three, or (4) four? (b) What are the principal quantum numbers of the initial and final states for this process? (c) ...Suppose a hypothetical atom had two metastable excited states, one 2.0 eV above the ground state and one 4.0 eV above the ground state. If used in a laser with transitions only to the ground state, (a) What is the ...What is the minimum energy of a thermal oscillator in a blackbody producing radiation at λmax at a temperature of 212oF? Why is the energy threshold for electron–positron pair production actually higher than the sum of their two masses (1.022 MeV in energy terms)? A particle in box is constrained to move in one dimension, like a bead on a wire, as illustrated in Fig. 28.16. Assume that no forces act on the particle in the interval 0 < x < L and that it hits a perfectly rigid wall. The ...
