ultraviolet rays

Invisible sun emission

Ultraviolet rays are electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays.

The sun emits ultraviolet rays, which cause sunburn and skin damage but also help the body produce vitamin D.

Artificial sources include tanning beds and blacklights.

Often shortened to UV rays or simply UV: UV exposure increases skin cancer risk.
