Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in the atom, just as it can only emit these discrete energies. When a spectrum is taken of the solar corona, in which a broad range of EM wavelengths are passed through very hot hydrogen gas, the absorption spectrum shows all the features of the emission spectrum. But when such EM radiation passes through room-temperature hydrogen gas, only the Lyman series is absorbed. Explain the difference.

Derive the approximate form of Heisenberg's uncertainty principle for energy and time, Eth, using the following arguments: Since the position of a particle is uncertain by x, where is the wavelength of the photon used to examine it, there is an uncertainty in the time the photon takes to traverse x. Furthermore, the photon has an energy related to its wavelength, and it can transfer some or all of this energy to the object being examined. Thus the uncertainty in the energy of the object is also related to . Find t and E ; then multiply them to give the approximate uncertainty principle.
