The majority of the sun's energy that reaches the Earth's surface is in the form of visible light radiation. Visible light is a form of electromagnetic radiation that is visible to the human eye. It consists of a range of wavelengths that correspond to different colors, from red to violet.

The sun emits energy across a broad spectrum of electromagnetic radiation, including infrared, ultraviolet, and other wavelengths. However, visible light makes up a significant portion of the sun's radiation that reaches the Earth's surface.

Visible light is essential for various biological processes on Earth, such as photosynthesis in plants, vision in animals, and overall environmental conditions. It provides the energy needed for life and plays a crucial role in maintaining the planet's ecosystems.
