Sun

Radiation Sun radiation is energy emitted from the sun in the form of electromagnetic waves. Sun radiation is composed of a range of spectrum including visible light, ultraviolet radiation, and infrared radiation. Sun radiation is a major source of energy for Earth, providing the energy for photosynthesis, warming the Earth's surface, and providing light for visibility. Sun radiation is also used in solar energy technologies such as photovoltaic cells and solar panels, which capture the energy from sunlight to generate electricity. Sun radiation is important for life on Earth as it is essential for photosynthesis and is essential for a wide variety of ecosystems.
