A photon of wavelength 320 nm is absorbed by a hydro-gen atom when the electron is in the second excited state. What is the speed of the ionized electron?
Answer to relevant QuestionsIf the minimum energy of a thermal oscillator in a blackbody’s most intense radiation is 3.5 x 10-19J, what is the Celsius temperature of the blackbody? 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) What is the de Broglie wavelength of the Earth in its orbit about the Sun? (b) Treating the Earth as a de Broglie wave in a large “gravitational” atom, what would be the principal quantum number, n, of its orbit? ...An electron in an atom is in an orbit that has a magnetic quantum number of mℓ = 2. What are the minimum values that (a) ℓ and (b) n could be for that orbit? If an excited state of an atom has a lifetime of 2.0 x 10-7 s, what is the minimum error associated with the measurement of the energy of this state?
