WebRadio waves in a vacuum travel at the speed of light. When passing through a material medium, they are slowed depending on the medium's permeability and permittivity. Air is … WebRADAR is a widely known form of active remote sensing. In radar, the instrument emits a radio wave and senses the returned energy which is reflected from the target. Since the speed of radio waves and the time delay between emission and return are known, the distance to the target can be determined.
