Worksheet: Natural Line Widths

In this worksheet, we will practice calculating the natural line width for a spectral line based on the Heisenberg uncertainty principle.

Q1:

Which of the following expressions does not violate the Heisenberg uncertainty principle?

  • AΞ”π‘₯Δ𝑝≀110ℏ
  • BΞ”π‘₯Δ𝑝β‰₯ℏ
  • CΞ”π‘₯Δ𝑝=ℏ10
  • DΞ”π‘₯Δ𝑝≀ℏ4
