Facts About Ultraviolet Radiation

In the 1950s there was a toy called the gilbert u 238 atomic energy laboratory that came equipped with low level radiation sources and four uranium bearing ore samples. Ultraviolet radiation is a form of energy that travels through space.

Uv light is usually invisible but depending on the conditions it can sometimes be seen down to about 310nm.

Facts about ultraviolet radiation. In the mountains because the air is cleaner and the thinner atmosphere absorbs less uv radiation. Uv levels increase by 10 12 with every 1000 metres increase in altitude. The benefits of uv rays.

Time of year or season. 11 15 interesting facts on radiation. The study found 5 of uv radiation uv rays passes through the umbrella with up to 35 reflecting off the sand around the seemingly shaded area and onto the skin.

Uv radiation is stronger at high altitudes ie. Uv light lies in the invisible spectrum hence the name black light. Between 400 nanometres and 4 nm.

It can damage or kill cells. Any electromagnetic radiation light that has a wavelength shorter than 450 nm may cause trouble. Uv rays all you need to know.

This part of the spectrum is undetectable to the naked eye with only a few insects capable of seeing it but its indirectly visible to us via fluorescent objects which emit the radiation at a lower energy level. While there are many artificial sources of uv radiation the sun is still the primary source of radiation in nature. Ultraviolet radiation that portion of the electromagnetic spectrum extending from the violet or short wavelength end of the visible light range to the x ray region.

It is called ultra violet because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the colour violet. Ultraviolet uv radiation is a part of the electromagnetic spectrum that extends from the end of visible light through to x rays. 1 uv light can damage the human skin.

Ultraviolet uv radiation is undetectable by the human eye although when it falls on certain materials it may cause them to fluoresceie emit electromagnetic radiation of lower energy such as visible light. Ultraviolet radiation uv electromagnetic radiation having wavelengths between that of violet light and long x rays ie. In the range 400300 nm the radiation is known as the near ultraviolet.

The angle of the sun varies depending on the time of year. Therefore humans that live in places with more ultraviolet light have adapted by getting darker skins. Want to learn more.

Ultraviolet light 10 interesting facts. The dangers of uv rays. Below are 46 fascinating facts relating to uv light and radiation that i have compiled.

Ultraviolet light is a type of ionizing radiation. It lies between the electromagnetic spectrum of x ray which is 40 nm and visible light 400 nm. Uv radiation is greatest in summer.
