ultraviolet light
Beyond visible purple
Ultraviolet light is electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays.
The sun emits ultraviolet light, which causes sunburn and skin damage but also helps the body produce vitamin D.
Artificial sources include tanning beds and black lights.
Often shortened to UV: UV rays, UV protection.
