we are moving away from a stationary cell phone tower at 25 m/s. If the frequency emitted by the cell tower is 5 GHz, what is most nearly the difference between the reflected frequency and the transmitted one? 1GHz = 10° Hz
While chasing the person who released all the ping pong balls, an astronaut is screaming at 694Hz while moving towards the miscreant at 5.2 m/s. The prankster is fleeing, but at only 3.1 m/s. The air on the ISS is kept pretty close to standard pressure and temperature, so the speed of sound is 343 m/s. At what frequency does the prankster hear the yell?
Do not actually solve the problem numerically or algebraically, just pick the one equation and define the relevant knowns and single unknown.
The speed of sound in air at room temperature is 343 m/s.
What is the frequency of a sound wave in air with wavelength 1.71 m (in Hz)?
What is the frequency of a radio wave with wavelength 1.71 m? (Radio waves are electromagnetic waves that travel at 3.00 × 108 m/s in air or in vacuum.)
