Ultraviolet light is on the electromagnetic spectrum - Leaving Cert Physics - Question g - 2020

High Energy/Frequency: Ultraviolet (UV) light has a higher frequency than visible light, which means it carries more energy. This property allows UV light to cause various chemical reactions, including the formation of free radicals.

Causes Ionization: Ultraviolet light is capable of ionizing atoms and molecules, which means it can remove tightly bound electrons. This property is significant in processes such as the formation of ozone in the atmosphere and in biological effects like DNA damage.
