Blacklight is a type of technology that uses ultraviolet (UV) light to reveal hidden information or features that are not visible under normal lighting conditions. It is commonly used in various fields, including forensics, art restoration, and security. For example, forensic scientists use blacklight to detect bodily fluids or trace evidence at crime scenes. In addition to its practical applications, blacklight is also popular in entertainment settings, such as nightclubs and theater productions. It creates a unique visual effect by making certain materials, like fluorescent paints and dyes, glow brightly. This captivating effect enhances the overall experience for audiences and participants.
