* Nuclear Fusion: The sun generates light through a process called nuclear fusion. Inside the sun, hydrogen atoms fuse together to form helium, releasing enormous amounts of energy in the form of light and heat.
* Electromagnetic Radiation: This energy travels to Earth as electromagnetic radiation, which includes visible light, infrared radiation (heat), and ultraviolet radiation.
* Sunlight: We perceive this visible light as sunlight, which illuminates our planet and allows us to see.
Without the sun, Earth would be a dark and frigid place.
