The Uncertainty Principle states that
 
  1) all measurements are essentially incorrect to some degree.
  2) no measurement is exact.
  3) we cannot in principle know both the position and momentum (or energy and time) of a particle with absolute certainty.
  4) science itself is essentially uncertain.
 
  The Uncertainty Principle is applicable
  5) only in the atomic domain.
  6) in all physical domains, from the nuclear to the cosmic.
  7) in all areas of good theory, scientific or otherwise.

Question 2

Refer to the figure above. Suppose that an electron makes a transition from n = 3 to n = 2 and emits a photon of frequency 4  1014 Hz. Then an electron that makes a transition from n = 3 to n = 1 may emit a photon with a frequency of
 
  1) 1  1014 Hz,
  2) 3  1014 Hz,
  3) 4  1014 Hz,
  4) 9  1014 Hz,
 
  which is consistent with emission of the most energetic photon from a transition from n = 3 to
  5) n = 1.
  6) n = 2.
  7) either, as both transitions are equivalent.
