Black light radiation
WebMar 18, 2024 · An object that absorbs ALL radiation falling on it, at all wavelengths, is called a blackbody. When a blackbody is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. This emission is called blackbody radiation. WebPhosphors are substances that emit visible light in response to radiation. Phosphors hit by UV light become excited and naturally fluoresce, or in other words, glow. In addition, although your eyes can't see the UV light …
