The property of reflection of electromagnetic waves is used in practice to determine the location of ships and aircraft, rockets and spaceships. A device that sends radio waves in a given direction and receives a reflected signal is called radars. Using a radar, the distance 1 to the aircraft is determined by measuring the time interval t between the moments of the departure of the electromagnetic wave and the return of the reflected wave The sought distance is 1 = s * t / 2
