Visible light is the light you can see. Various light wavelengths appear in different colours to you such as red, blue, green, and yellow. The light has more energy if the wavelength is also higher.

UV light has more energy compared to visible light, which means that it has a higher wavelength. Your naked eye cannot see it.

When switched on, black light may appear as dark purple. This is because blue or purple is the highest visible light wavelength you can see. Other emitted lights are invisible to you.

Either way, UV light interacts with phosphors. These are luminescent substances. They absorb energy and release this as light. Teeth and nails, detergents, some types of ink are good examples of phosphors.
