Black light, also known as ultraviolet light (UV), works by emitting light in the ultraviolet spectrum. This light has a shorter wavelength than visible light, allowing it to excite certain molecules and substances that are not visible under normal lighting conditions. When UV light is absorbed by these substances, it causes them to emit visible light, producing a glowing effect known as fluorescence. This phenomenon is used in various applications, including forensics, art and entertainment, and insect attraction.

The emission of visible light from the absorption of ultraviolet light occurs due to the electronic transitions from excited states to ground states. This process is known as photoluminescence, which is the release of energy in the form of light. The color emitted by the substance depends on its unique molecular structure and the amount of energy absorbed and emitted. For example, some substances emit a bluish-purple color, while others emit a greenish-yellow color.

It is important to note that not all substances are capable of fluorescing under UV light. Some substances, such as metals, do not have the necessary electronic structure to emit light. Therefore, when using UV light for specific applications, it is important to understand which substances are capable of fluorescing and which are not.
