Suppose you send a probe to land on Mercury, and the probe transmits radio signals to earth at a wavelength of 64.0000 cm. You listen for the probe when Mercury is moving away from Earth at its full orbital velocity of 48 km/s around the Sun. What wavelength (in cm) would you have to tune your radio telescope to detect that signal? (Hint: Use the doppler shift formula, (Note: the speed of light is 3.0 x 10 km/s. Give your answer to at least four decimal places.)

There is one part to this question. I have tried 64.102 and that is wrong. Please help!

Suppose you send a probe to land on Mercury, and the probe transmits radio signals to Earth at a wavelength of 64.0000 cm. You listen for the probe when Mercury is moving away from Earth at its full orbital velocity of 48 km/s around the Sun. What wavelength (in cm) would you have to tune your radio telescope to detect that signal? (*Hint: Use the Doppler shift formula, \( \frac{V_r}{c} = \frac{\Delta \lambda}{\lambda_0} \)*)

(*Note: the speed of light is 3.0 x 10^5 km/s. Give your answer to at least four decimal places.*)

\[ \boxed{\phantom{64.1234}} \] cm
