in general high or low frequency will have a shorter or longer wavelength Atmospheric science mainly studies wavelengths, namely solar shortwaves. long wave terrestrial and long waves in the atmosphere If the temperature of the object increases The stronger the radiation ability of that object. when the temperature drops The wavelength corresponding to the maximum black body radiation. It will move to the direction of the long wave. We all know that The speed of light is 300 million meters per second. Based on this data, the operating frequency of Doppler radar with a wavelength of 10 centimeters can be calculated to be 3000 million hertz.
