Why aren't black lights black?
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.
Can a black light be a flashlight in a dark room?

Do black lights exist and how do they work?
Yes, black lights exist. They emit ultraviolet (UV) light, which is not visible to the human eye.

This is how black lights make objects appear to glow in the dark.
