do radio waves penetrate the earth's atmosphere
Radio wave Radio waves in vacuum travel at the speed of light.[7][8] When passing through a material medium, they are slowed according to that object's permeability and permittivity. Air is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light.
Sunlight On Earth, the solar radiation varies with the angle of the sun above the horizon, with longer sunlight duration at high latitudes during summer, varying to no sunlight at all in winter near the pertinent pole. When the direct radiation is not blocked by clouds, it is experienced as sunshine. The warming of the ground (and other objects) depends on the absorption of the electromagnetic radiation in the form of heat.
Geographical zone On the basis of latitudinal extent, the globe is divided into three broad heat zones.
