there are two types of ultraviolet rays UVA and UVB
Ultraviolet
The ultraviolet rays in sunlight destroy cells in the outer layer of the skin, damaging tiny blood vessels underneath. When the skin is burned, the blood vessels dilate and leak fluid. Cells stop making protein. Their DNA is damaged
"sunburn" results from physical damage caused to your skin by overexposure to Ultraviolet emissions, usually from the sun but it can also come from a UV lamp. UV light affects damage to the DNA of your skin cells. In defense those cells will produce melanin, a chemical response to try to repair this damage, which also darkens the color of the skin ( a "sun tan").
In general, it is ultraviolet light (the UV ray) that causes sunburn. Ultraviolet light is of a higher frequency than visible light, which means shorter wavelength, and higher energy. UV rays tend to do some tissue damage and burn skin causing sunburn.
No. I believe you're thinking of ultra-violet.
