34: Estimate the speed of satellites
Here's what the NOAA-15 weather satellite sounds like, by the way! *tick-tock*
While recording, I noticed something strange: The transmission didn't happen at the frequency I had expected it to! And the frequency changed.
Then it hit me: Doppler effect! At the time of the recording, the frequency was around 4250 Hz higher than expected.
After looking up the formula, I calculated a relative speed of 9 km/s! (Which got close to its real speed, 7.5 km/s.)
