Question: The hydrogen spectrum has a series of lines called the
The hydrogen spectrum has a series of lines called the Lyman series, which results from transitions to the ground state. What is the longest wavelength in this series, and in what region of the EM spectrum does it lie?
Answer to relevant QuestionsA hydrogen atom absorbs light of wavelength 486 nm. (a) How much energy did the atom absorb? (b) What are the values of the principal quantum numbers of the initial and final states of this transition? Show that the orbital speeds of an electron in the Bohr orbits are given (to two significant figures) by vn = (2.2 x 106 m/s/n). Consider an electron in its first excited state in a hydrogen atom. Determine its (a) Orbital speed, (b) Angular speed, (c) Linear momentum, and (d) Angular momentum. A bowling ball has well- defined position and speed, whereas an electron does not. Why? (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? ...
