- - - - Objects moving AWAY from detector
        
        lower frequency
        
        higher wavelength
        
        Flow away from detector = BLUE
      - Objects moving TOWARDS detector
        
        higher frequency
        
        lower wavelength
        
        Flow toward detector = RED
