(b) SuppoSe that you are in the equatorial plane of Venus and you bounce a vo = 1GH2 radar signal off the entire planet. What is the spread in frequen- cies of the returned signal? (Neglect any Doppler shift due to the motion of che planet as a whole.) Hint: In applying Doppler effect in electromagnetic waves, the motion of che source is equivalent to the motion of the observer (unlike in the case of Doppler shift in sound waves). What it matters in em waves is the rel- ative motion between the two. If a source/an observer is moving toward an observer/a source, the observed frequency is higher producing a Doppler blueshift. On the other hand, If a source/an observer is moving away from an observer/a source, the observed frequency is lower producing a Doppler redshift.]

Question

The rotation speed of Venus was first measured with ground-based radar.

(b) Suppose that you are in the equatorial plane of Venus and you bounce a Vo = 1GH2 radar signal off the entire planet. What is the spread in frequen- cies of the returned signal?
