<h3>What is white light?</h3>
We use "white light" as a term to describe the combination of all colors of light in the spectrum. The sun emits all colors of light, when this light hits an object, most of the colors are absorbed. The color that does not get absorbed is reflected back and causes us to perceive the object in that color.
Therefore, we can confirm that sunlight is white light, when it shines on a red object the red wavelength is reflected. The other colors are absorbed, so the only thing you see is the red light reflected back.
