Eq. 2.55 describes the shape of a wave pulse. The Fourier
transformation of the pulse is given by Eq. 2.62. How are
the widths of the pulses related? That is, if I increase the
width of the pulse in space, what happens to the width of its
wave number distribution?
Are there topics that will be covered on Exam 1 that you would
like us to review in class on 2/17?
