When you are going to be out in the sun for a long period, wear sunblock, and spend some time in the shade when you can.
To choose a sunblock, the SPF rating tells you the multiple for how long you should be able to be in the sun. e.g. SPF 10 multiplies how long you can be in the sun without burning by 10.
This is not an easy number to know any true value for. Every person burns at a different rate, every time you step into the shade for a couple minutes it helps prolong this time, and how direct the sun is, as well as many other factors can lengthen or shorten how long it will take to burn.
You can protect yourself. You have to wear sunscreen.
You have that a bit backwards- the ozone Layer of the Earth's atmosphere protects your skin- by blocking ultraviolet light from the sun. If the ozone layer is reduced, you are exposed to more UV light. You protect yourself from THAT with sunscreen, a hat, long sleeves, and by staying in the shade.
Glass is transparent to visible light but absorbs ultraviolet (UV) radiation. This is why glass can protect against UV rays from the sun, which can be harmful to both humans and materials.
No. They can not see in ultraviolet light. They are known to glow when exposed to ultraviolet light, though.
Ozone (which is O3). It helps protect from ultraviolet light.
No, most of the Sun's ultraviolet light is absorbed by the Earth's atmosphere, particularly by the ozone layer. Only a small fraction of ultraviolet light reaches the Earth's surface, which is why it is important to protect ourselves from its harmful effects with sunscreen and protective clothing.
Ultraviolet light. That's why it's called so.
The wavelengths of visible light are longer than ultraviolet wavelengths.
as i know its destroyed by ultraviolet light
ultraviolet light.
No, ultraviolet light does not attract mosquitoes.
Ultraviolet light can damage the cornea and lens of the eye, potentially leading to conditions such as cataracts or corneal sunburn. Prolonged exposure to ultraviolet light can also increase the risk of developing eye diseases such as macular degeneration. It is best to protect your eyes with sunglasses that block UV radiation when outside.
