Doppler radar works on the principle that, as precipitation moves toward or away from the antenna, the ____.
A)light beam will measure the wind speed of tornadoes
B)light beam will measure the change in frequency of falling precipitation
C)returning radar pulse will change color compared to the transmitted frequency
D)returning radar pulse will change frequency compared to the transmitted frequency
E)returning radar pulse will be the same frequency as the transmitted frequency

Question

Quizplus · Accepted Answer

Doppler radar operates on the Doppler effect principle, where the frequency of the returning radar pulse changes compared to the transmitted frequency when the object (in this case, precipitation) moves toward or away from the radar. This change in frequency is used to measure the velocity of the precipitation particles, which helps in determining the speed and direction of weather systems.
