On the definition of width in Doppler broadening problems.

  1. Nov 4, 2016 #1
    The following question has stumped me. I am not getting the answer marked. Instead I am getting option a). I have produced my attempt below.

    Also I have no idea which formula to use when the question says Doppler width. Since frequencies form a distribution, there are multiple notions of width. Is there a standard notion for the term Doppler width in broadening problems?

    You use the one most appropriate to the context.

    I see what you mean. It will have to depend on the course the test was for.
