Where fs is the frequency of the source and fo is the observed frequency. Again, the top sign is associated with objects moving towards each other and the bottom sign associated with moving away. Suppose a space probe emits a radio signal at a frequency of 4.500000 MHz (Megahertz). It travels away from Earth with a speed of 2.000Γ104 m/s. What is the frequency of the signal when it is detected on Earth? (Note: give 7 significant digits)
