Solar radiation

Solar radiation is electromagnetic radiation emitted by the Sun into space. It is the basic source of energy for the Earth and an important factor influencing its climate and environment. Solar radiation is composed of various types of electromagnetic radiation, including visible light, ultraviolet (UV) radiation, and infrared (IR) radiation.

Visible light is only a small part of sunlight and includes the various colors of the visible spectrum, such as red, orange, yellow, green, blue, indigo and violet. UV radiation is invisible to the human eye and has high energy. A small amount of UV radiation is useful for the formation of vitamin D in human skin, but excessive exposure can be dangerous to health and cause skin damage.

Infrared radiation is also invisible to the human eye and has long wavelengths. This radiation carries thermal energy and is responsible for heating the surface of the Earth and the atmosphere.

Solar radiation is important for life on Earth because it is the primary source of energy for plant photosynthesis, which provides oxygen and nutrients for most organisms. It is also the basis for the creation of climate and weather on Earth. It is also used for the production of solar energy, solar panels and other technologies that use solar energy to produce electricity or heat.
