Yes, the sun emits ultraviolet (UV) light. UV light is a type of electromagnetic radiation that lies between visible light and X-rays on the electromagnetic spectrum. The sun emits UV light in three different bands: UVA, UVB, and UVC. UVA rays are the least harmful and can penetrate the skin the deepest, while UVC rays are the most harmful but are mostly absorbed by the Earth's atmosphere. UVB rays are responsible for sunburns and can also damage the DNA in skin cells, leading to skin cancer.
