What are ultraviolet waves?
The light is made of waves and particles. The speed at which these waves of oscillates determine what type of wave is. The ultraviolet waves (UV waves) are waves that are shorter than the purple light-the first light waves can detect our eyes. Ultraviolet waves are between 100 and 4000 angstroms (10-400 nanometers). This is shorter than visible light, but longer than X -rays and gamma rays.
The shorter the wave in the spectrum, the more energy it has and the faster it oscillates. The more energy the wave, the more dangerous it is. Higher energy means that the waves can penetrate further into the human body and cause greater damage. Ultraviolet, X -rays and gamma rays are waves that are shorter on the light spectrum than purple. While all three can be harmful to people, ultraviolet waves have become the most famous.H good or bad thing, because ultraviolet waves are useful and harmful. Some animals like bees can detect uv light and see special patterns in flowers, toTeré leads them to the source of nectar. In addition, waves can also provide scientists with a different view of the universe. With specialized cameras and equipment, scientists are able to study the sun, stars and various objects on our own planet.
Another advantage for ultraviolet light is its ability to sterilize. UV waves are used in air and cleaning water as a way of erading bacteria and viruses. Waves are also helpful in the production of vitamin D. When UV wool hit the skin, they stimulate the production of vitamin. Although it is true that the UV waves contribute to the production of vitamin D, it is important that you do not submit too much to any form of ultraviolet light.
One of the most common damage caused by UV waves is burning. When the waves hit the skin, they can damage or kill skin cells. Over time, the excessive exposure to UV waves can also lead to skin cancer. Because the burning is caused by ultravioletIt is even possible to burn burns on a cloudy day; It is important to wear appropriate protection all the time. Limiting the exposure to ultraviolet waves throughout life can help people avoid these disastrous side effects.
