What kind of light does the Sun emit?
The Sun emits a variety of 'colors' of light. Just as there are noises that people cannot hear, most of the 'colors' of light that the Sun emits are invisible to humans. Visible light is what we can see with our eyes. It contains every hue of the rainbow: red, orange, yellow, green, blue, and purple. The energy content of red light is lower than that of the other hues in the rainbow. Then follows orange, then yellow, and finally purple, which has more vitality than the previous hues.
The Sun emits light with even greater energy than purple. One form of this light is ultraviolet (UV), and it can cause sunburn. X-rays, which you get when you go to the dentist, are another sort of high-energy light. X-rays are also light! We simply cannot see them. Infrared, microwave, and radio light have less energy than visible light. Your microwave uses microwave light that we cannot see to heat your meal. When you turn on a radio, you are emitting a form of light that you cannot see. All of these types of light are emitted by the Sun and the stars!
