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?
