A meteorologist for a TV station is using radar to determine the distance to a cloud. He notes that a time of 0.24 ms elapses between the sending and the return of a radar pulse.
How far away is the cloud?
A police officer's radar gun emits radio waves at a frequency of 10.5 GHz. What is the difference in the frequencies (Hz) reflected back to the radar gun by a car traveling at the 55 mph speed limit and a car travelling 1 mph faster? Assume that the cars are both headed directly away from the stationary officer.
Gamma-ray bursters are objects in the uni-
verse that emit pulses of gamma rays with
high energies. The frequency of the most en-
ergetic bursts has been measured at around
3.0 x 1021 Hz.
The speed of light is 3 x 10° m/s.
What is the wavelength of these gamma
rays?
Answer in units of m.

The timing of the synchronization signal is controlled by a set of atomic clocks to an accuracy of 101012 s, and repeats every 1 minute. The signal is used for devices, such as radio-controlled watches, that automatically synchronize with it at preset local times. WWVB's long wavelength signal tends to propagate close to the ground.

The speed limit is 29.1 m/s. A police car radar "clocks" the speed of the other car by emitting microwaves with frequency 6.20 × 1010 Hz and observing the frequency of the reflected wave. The reflected wave, when combined with the outgoing wave, produces beats at a rate of 1400 s-1. If the speeder is going faster than the police car, how fast would it have to go so that the reflected microwaves produce the same number of beats per second? m/sarrow_forwardA spacecraft landing on the Moon uses the Doppler effect on radar signals transmitted at a frequency of 5 GHz to determine the landing speed.
