Voyager 1 was launched by NASA in 1977 and has been moving away from the Earth since that date.

As of 3/23/2023, it was r = 1.992 x 1013 m from Earth. In order to send data back to Earth, Voyager 1

emits electromagnetic waves at a frequency of 8.40 GHz and power of 22.4 W. Due to Voyager 1's velocity relative to Earth, when NASA receives the data, the frequency is 0.43 MHz less than when it was emitted. Find:

A) the wavelength of the emitted electromagnetic wave

B) the type of EM wave (GXUVIMR)

C) the speed of Voyager 1 relative to Earth (note: keep at least 6 sig figs in your intermediate steps in order to get an accurate value)

D) if Voyager 1 emitted equally in all directions, the intensity of the electromagnetic wave when it

arrives at Earth would be given by I = P/(4m*). Since Voyager 1 has a 48 Bi high gain directional

antenna pointed straight at earth, the intensity is instead 1=10*. Find this intensity.
