Black light, also known as Wood's light, are bulbs and lamps that emit electromagnetic radiation. These radiations are of ultraviolet wavelengths and provide very little light that we can see. Black light bulbs produce a dim purple color light and are excellent to make things glow in the dark.
Black light bulbs generate ultra violet light that causes some materials like phosphors to shine and to emit visible light. It is said about black light bulb that if a person strolls around a place at night with a portable black light then he would find phosphors all over the place. We have natural phosphors in teeth and fingernails. Most laundry detergents too contain phosphors to make clothes shine in daylight. Sunlight contains ultraviolet light that causes the clothes with phosphor particles over them to appear whiter in daylight.

Light bulbs in Black and White
The light produced by Light bulbs is a mixture of different colors and wavelengths. Some bulbs like green lights produce only green colored light while white light contains all of the colors. When we see an object, what we are seeing is actually the colors of light that are reflected off that object. White objects appear white as they reflect all the colors while none of the color is reflected by black material resulting in black color. On putting a white under a red light, it would appear red.
The only way to get a white object to look white is if we shine white light on it. But since white light have all the colors in it, other objects can still appear to be different colors depending on which parts of the white light they reflect. To make things look only black or white, objects have to reflect all of the colors or none of them.
