If someone experiences a sunburn, which type of ultraviolet radiation is likely responsible?

Sunburns are primarily caused by UVB radiation, which is a type of ultraviolet light that has a shorter wavelength than UVA rays. UVB is the most significant cause of skin reddening and sunburn, with its intensity being higher during peak sunlight hours. It is also known for damaging the outer layers of the skin, leading to the painful and often blistering effects of sunburn. UVA radiation, while it penetrates the skin more deeply and is associated with long-term skin damage and aging, plays a lesser role in the immediate effects of sunburn. UVC radiation, on the other hand, is mostly absorbed by the Earth’s atmosphere and does not normally reach the skin. Lastly, visible light does not have the properties required to cause sunburn, as it lacks the necessary energy to damage skin cells.
