Chapter 26, Problem 72RPP

To determine

The frequency closest to the frequency $f_O$ which is detected by the radar when the waves come after reflection from the tennis ball, given that the speed of served ball is $57\text{ m/s or 127 mi/h}$ from the options given below

(a) Exactly $10.525\text{ GHz}$

(b) $10.525\text{ GHz + 4}\text{.0}\times {\text{10}}^{-6}\text{ GHz}$

(c) $10.525\text{ GHz }-\text{ 4}\text{.0}\times {\text{10}}^{-6}\text{ GHz}$

(d) $3\times {10}^{-7}\text{ Hz}$
