UV light

Tanning bed emission

UV light is ultraviolet light—electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays.

Most UV light comes from the sun; it causes sunburns and skin damage but also helps the body produce vitamin D.

Artificial UV light is used in tanning beds, sterilization equipment, and black lights that make certain materials fluoresce.
