Question 8
Step by step
Solved in 2 steps
- A Doppler weather radar station broadcasts a pulse of radio waves at frequency 2.85 GHz. From a relatively small batch of raindrops at bearing 38.6 east of north, the station receives a reflected pulse after 180 s with a frequency shifted upward by 254 Hz. From a similar batch of raindrops at bearing 39.6 east of north, the station receives a reflected pulse after the same time delay, with a frequency shifted downward by 254 Hz. These pulses have the highest and lowest frequencies the station receives, (a) Calculate the radial velocity components of both batches of raindrops. (b) Assume that these raindrops are swirling in a uniformly rotating vortex. Find the angular speed of their rotation.10² 106 Increasing frequency, f (Hz): 104 106 1 Radio waves (low f, longa) AM 104 10² Decreasing wavelength,λ (m) 108 FM TV 1 1010 Microwave Radar 10-2 10¹2 700 nm 10-4 1014 Infrared 10-6 600 nm 1016 Ultra- violet 10-8 Visible light 1018 X rays 10-10 500 nm 1020 1022 Gamma (y) waves (high f, short 2) 10-12 10-14 400 nm 1024What is the frequency of the EM radiation with a wavelength 3000 nm? 5.0 x 1013 Hz 1.0 x 1014 Hz O.1.0 x 1015 Hz 5.0 x 1014 Hz O1.67 x 1013 Hz
