Definition of solar radiation

Solar energy is nuclear fusion process that occurs in the sun. This energy is the primary energy source and, therefore, the engine that drives our environment. Solar energy is directly or indirectly responsible as important to life as photosynthesis, maintaining a temperature of the planet supports life, vient, etc. aspects Solar energy reaching the Earth's surface is 10,000 times the energy currently consumed by all humanity.

Radiation is the transfer of energy by electromagnetic waves. The radiation is produced directly from the source outward in all directions. These waves do not need a material medium to propagate, can pass through interplanetary space and reach Earth from the sun.

The wavelength and frequency of electromagnetic waves are important in determining their energy, their visibility and penetration power. All electromagnetic waves travel in vacuum at a speed of 299,792 km / s.

These electromagnetic waves can have different wavelengths. The set of all wavelengths is called electromagnetic spectrum. All the wavelengths emitted by the sun is called solar spectrum.

The proportion of solar radiation in different regions of the spectrum is about

Ultraviolet: 7%
Visible Light: 43%
Infrared: 49%
The rest: 1%
