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?

  • A Ξ” π‘₯ Ξ” 𝑝 ≀ 1 1 0 ℏ
  • B Ξ” π‘₯ Ξ” 𝑝 ≀ ℏ 4
  • C Ξ” π‘₯ Ξ” 𝑝 β‰₯ ℏ
  • D Ξ” π‘₯ Ξ” 𝑝 = ℏ 1 0
