A wave traveling at 5.0 x 10^4 meters per second has wavelength of 2.5 x 10^1 meters. What is the frequency of the wave?
2.0 x 10^3 Hz
5.0 x 10^-4 Hz
5.0 x 10^3 Hz
1.25 x 10^6 Hz
As the frequency of a wave increases, the period of that wave
remains the same
increases
decreases

A police officer's stationary radar device indicates that the frequency of the radar wave reflected from an automobile is less than the frequency emitted by the radar device. This indicates the automobile is
moving toward the police officer
moving away from the police officer
not moving
