Sunlight is reflected, absorbed, and transmitted by Earth's atmosphere. Which are the chief constituents of the electromagnetic energy that reaches Earth's surface is Ultraviolet Light and Visible Light, to understand more....
Types of solar radiation
Solar radiation is divided into three types, which are classified according to wavelength and intensity:
- Visible
- Ultraviolet
- and Infrared.
Visible radiation
Radiation gets its name because it is visible to humans. It is the simplest form of electromagnetic radiation and concentrates much of the energy that comes from the sun.
Ultraviolet radiation
Ultraviolet radiation contains the least amount of solar energy. Its wavelength is shorter and for that reason it is not visible.
Infrared radiation
Infrared radiation contains most of the solar energy, reaching almost 50%, and is also not visible to humans. Its length varies between 780 nm and 1 mm, which means that it is longer than light.
With this information, we can conclude that the electromagnetic energy that reaches the Earth's surface is ultraviolet light and visible light.
