Homework Help: Estimating Doppler Shift for a Radio Wave

  1. Dec 6, 2011 #1
    1. The problem statement, all variables and given/known data

    Estimate the Doppler shift for a radio wave reflected from an airplane moving directly toward you at a speed of 292 m/s. Assume the radio wave has a frequency of 9.7x10^6 Hz.

    2. Relevant equations

    fo = fv/(v − vt)

    3. The attempt at a solution

    Using the above equation I got 1.9e5 Hz. But, that is incorrect. Am I not using the correct equation?

    Thanks, Delphi. In my textbook, doppler shift is covered 2 pages, and thus of little use.
