1. The problem statement, all variables and given/known data A radar beam has a wavelength of .02 m. The frequency is 17500 Hz. What would be its echo frequency if a rocket 60km away is moving at 500m/s and the radar is coming from a jet moving at 310m/s towards the rocket which is aimed at it? (b) Would the rocket appear red shifted or blue shifted? (c) Which would be shifted more, a sound wave or a light wave? 2. Relevant equations [fo/vw + vo] = [fs/vw + vs] 3. The attempt at a solution [fo/vw + vo] = [fs/vw + vs] = [fo/ (350 + 310 + 500)] = [17500/ (350 + 310 - 500)] fo = 126875Hz (b) Blue shifted (c)Sound wave Is this correct?
