What is the role of a transponder in satellite communication?
Correct Answer: A transponder receives signals at one frequency, amplifies them, and then converts them to another frequency for transmission back to Earth.
Step 1: A transponder is a device located on a satellite.
Step 2: It receives signals from Earth at a specific frequency.
Step 3: The transponder amplifies (makes stronger) these received signals.
Step 4: After amplifying, it changes the frequency of the signals to a different one.
Step 5: Finally, the transponder sends the modified signals back down to Earth.
