UV radiation
Skin-damaging light waves
UV radiation is ultraviolet radiation—electromagnetic waves with wavelengths shorter than visible light but longer than X-rays.
Most UV radiation reaching Earth comes from the sun.
It causes sunburn, skin aging, and skin cancer, but also triggers vitamin D production.
Sunscreen blocks UV rays.
UV lamps are used for sterilization and curing certain materials.
