What are some examples of UV light?

Some other common ultraviolet light examples are:

• Black lights produce UV-A radiation along with some visible light. These are generally used as fluorescent lamps.
• UV light-emitting diodes (LEDs) generally emit UV-A or UV-B.
• Germicide lamps emit UV-C which disrupts DNA base pairing.

What protects from UV light?

To protect yourself from UV radiation: Wear a wide brim hat to shade your face, head, ears, and neck. Wear wraparound sunglasses that block both UVA and UVB rays. Use sunscreen with sun protection factor (SPF) 15 or higher, for both UVA and UVB protection. Avoid indoor tanning.

How do you make a UV light?

UV radiation is produced either by heating a body to an incandescent temperature, as is the case with solar UV, or by passing an electric current through a gas, usually vaporized mercury. The latter process is the mechanism whereby UV radiation is produced artificially.

Is the sun ultraviolet light?

Sunlight is the main source of UV radiation, even though UV rays make up only a small portion of the sun’s rays. Different types of UV rays reach the ground in different amounts. About 95% of the UV rays from the sun that reach the ground are UVA rays, with the remaining 5% being UVB rays.

Do clothes protect from UV?

Clothes provide different levels of UV protection. Long-sleeved shirts, long pants, or long skirts cover the most skin and are the most protective. Dark colors generally provide more protection than light colors. A tightly woven fabric protects better than loosely woven clothing.
