WebMicrowaves are a subset of radio waves and includes frequencies ranging from around 300 million cycles per second (300 MHz) to 3 GHz. RF exposures are directly linked to absorption and distribution of RF energy in the body, and the absorption and distribution are strongly dependent on body size and orientation and on frequency and polarization of the … Web1 okta represents a cloud amount of 1 eighth or less, but not zero. 7 oktas represents a cloud amount of 7 eighths or more, but not full cloud cover. 8 oktas represents full cloud cover with no breaks. 9 oktas represents sky obscured by fog or other meteorological phenomena. A laser cloud base recorder is used to estimate partial cloud amount.
