A black light emits ultraviolet (UV) light, which is invisible to the human eye. When UV light hits certain substances, they absorb the light and re-emit it in a visible glow, creating the effect of fluorescence. This is why certain objects or materials appear to glow under a black light. The main purpose of a black light is to create this fluorescence effect, which is commonly used in entertainment, forensics, and counterfeit detection.
