Here's why:

* Star: The Sun is a giant ball of hot gas that produces its own light and heat through nuclear fusion.

* Visible light: This is the light we can see with our eyes, responsible for the colors we perceive in the world around us.

* Infrared radiation: This is heat radiation, which we feel as warmth.

* Ultraviolet radiation: This is invisible to the human eye and can be harmful in large doses.

So, while the Sun emits many types of light, it's most commonly associated with visible light, which is what allows us to see and experience the world.
