Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, but they differ primarily in wavelength and visibility to the human eye.
Here are two key differences:
-
Wavelength: UV light has a shorter wavelength than visible light. The shorter the wavelength, the higher the energy.
-
Visibility: Visible light is detectable by the human eye, while UV light is invisible to humans. Some insects, like bumblebees, can see UV light.
