Web15 sep. 2024 · d = distance of Earth to Moon in metres. c = the speed of light, 3 x 10 8 metres per second. t =time delay in seconds. The radio signal covers the same distance twice (Earth to the Moon, and back), hence the need to divide by 2. For example, with a delay time of 2.56 seconds: d = [ (3 x 10 8) x 2.56] / 2. d = 348 000 000 m. WebGround waves occur as the signal spreads out from the trans-mitter in all directions. Instead of traveling in a straight line (and not being heard beyond the visual horizon), radio signal tends to follow the curvature of the Earth. This occurs because currents are induced in the surface of the Earth, which slows the wavefront near the ground. how to uninstall scangear
