predicted the existence of the ionosphere, an electrically conductive layer in the upper atmosphere that reflects radio waves.

In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere.

Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. The atmosphere thins out in each higher layer until the gases dissipate in space.

Earth's atmosphere is similar to a jacket for our planet. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere.

The different layers of the atmosphere. The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.

Answer Expert Verified The part of the electromagnetic spectrum closest to radio waves is microwaves. The wavelength of radio waves ranges from 10 cm to more than 1 km.

Layers of the Earth's Atmosphere The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.

The thermosphere is often considered the "hot layer" because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect radio waves directed into the sky back toward the Earth. Radio waves directed at an angle into the sky can return to Earth beyond the horizon.

A lot of the electromagnetic radiation is absorbed by the atmosphere, with the exceptions of radio waves, microwaves, and visible light. While infrared and ultraviolet radiation are mostly absorbed by the atmosphere, they are also capable of penetrating the atmosphere at some wavelengths.

From highest to lowest, the five main layers are: Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles)

Stratosphere 10–31 Miles - The ozone layer lies within the stratosphere and absorbs ultraviolet radiation from the Sun. Troposphere 0–10 Miles - The troposphere is the layer of the Earth's atmosphere where all human activity takes place.

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). ... Naturally occurring radio waves are emitted by lightning and astronomical objects.

Electromagnetic radiation is reflected or absorbed mainly by several gases in the Earth's atmosphere, among the most important being water vapor, carbon dioxide, and ozone. Some radiation, such as visible light, largely passes (is transmitted) through the atmosphere.

These layers are the troposphere, stratosphere, mesosphere and thermosphere.

Earth's atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
