[True or False] 6 False [Statement] 
All satellites collect data by shooting laser beams down and measuring the reflections that come back. Some satellites measure reflected solar, laser, or radar energy or emitted thermal radiation coming from Earth. It is important to study many different wavelengths of radiation because each wavelength can provide more information about conditions of the surface that emitted or reflected the radiation.
