Which type of UV radiation is known for causing burning?

UVB radiation is known for its role in causing sunburns. This type of ultraviolet light has a shorter wavelength compared to UVA and penetrates the skin more superficially, affecting the outermost layers. When the skin is exposed to UVB rays, it can lead to the release of inflammatory substances that manifest as redness and burning sensations. This reaction is a response to the damage caused at a cellular level, which can lead to peeling and even long-term skin issues.

While UVA also contributes to skin damage and can lead to tanning, it is primarily linked to deeper skin effects and photoaging rather than the immediate burning sensation. UVC radiation, though considered harmful, is mostly filtered out by the Earth's atmosphere and does not typically reach the skin. Visible light, on the other hand, falls outside the UV spectrum and does not have the same harmful effects associated with UV radiation. Hence, UVB is the primary cause of burning due to its interaction with the skin.
