What is Ultraviolet (UV)?
Sunlight has long since been known to kill micro-organisms. The rays from the sun contain the UV Spectrum used in Ultraviolet Water Treatment Systems - although at much lower intensities. Ultraviolet (UV) is a safe, clean, easy-to-maintain method of assuring that water is free of bacteria. UV Water Purification uses Ultraviolet light, just like sunlight, to kill micro-organisms that may be in the water.

Ultraviolet light (UV light) is light of shorter wavelength than the visible spectrum. Many insects, like bees, see mostly UV light so they can find plants with nectar. Sunlig…ht contains UV light and can tan but also damage your skin if you stay outside too long on a sunny day. Answer: Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher frequency and infrared is lower. Note: Higher frequencies are shorter wavelengths and lower frequencies are longer wavelengths. Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher and infrared is lower
How UV Clear Pool Sanitizers Work Let's begin with your pool equipment. In order for your pool water to be cleaned it must be circulated. The pool pump is …the source for circulating the pool water. The pump draws water from the pool and is directed to the filter. The filter does exactly what it is named for. It traps particles and debris. After the water is filtered it is directed to your UV Pool Sanitizer. The filtered water enters the inlet of the UV System. Water flows through the length of the UV chamber. It is inside the chamber that microorganisms absorb powerful UV light. It is this light energy that destroys or inactivates these 'bugs'. A majority of residential pool owners use some form of chlorine to sanitize the water. They normally maintain anywhere from 1 part per million to 3 part per million (ppm) in chlorine. With the addition of UV Systems you can now save up to 70% in the cost of chlorine. Wouldn't it be encouraging to know that you can rely on your UV System when the sanitizer level falls below the norm? Once the water leaves the UV chamber it is returned to your pool. Many pools have a chlorine feeder which can be metered so you can control the level of chlorine. The amount of chlorine in the pool water is called sanitizer residual. We have field studies and reports from customers that are maintaining their chlorine residual at 0.3 part per million (ppm), 0.5 ppm and 1.0 ppm. It's possible that your drinking water could have a chlorine reading higher than .3 ppm. Pool owners that have sensitivity issues toward chlorine can now enjoy the benefits of UV System by maintaining a lower than normal chlorine residual. If given a choice wouldn't you rather swim in less chemicals anyway? Swim in a clean fresh smelling swimming pool with UV .
The prefix for ultraviolet is ultra because violet is the base/root word and ultra is the prefix!:0/:o ==
UV radiation is of a high energy, therefore it can cause damage to living cells. The dangers faced by humans include; most commonly damage to the skin, but also damage to the …eye and immune system. Most people experience sunburn at some time in their lives, but UV can cause more serious skin damage such as cancer as a result of DNA damage.
Skin cancers and cataracts are increasing throughout the world. Many scientists believe that these and other serious health problems are now due to decreasing lev…els of ozone in the upper atmosphere and increasing levels of ultraviolet radiation reaching the Earth' surface, as well as the growth in outdoor work and recreation activities.
Yes but very hard to find and expensive
Ultraviolet telescopes are similar to optical reflecting telescopes, but their mirrors have special coatings that reflect ultraviolet light very well. Ultraviolet telescopes p…rovide much information about interstellar gas, young stars, and the gaseous areas of active galaxies.
U.V can be separated according to its energy level and wavelength with UVa having the lowest energy and longest wavelength followed by UVb and ultimately UVc which has the sho…rtest wavelength and highest energy level. You may be familiar with UVa and UVb as the part of the suns rays which cause tanning, aging, and skin cancer. The Sun also emits UVc the most powerful and dangerous type of U.V., fortunately for us most of this is stopped in the upper atmosphere by gasses like ozone.
The disadvantage are that it can cause skin cancer if you are exposed to sufficient amounts of UV light (in particular, UV-B and UV-C light). See the Related Questions link to… the left of this answer for more information about that: "How do UV-B rays affect people?" One of the beneficial uses of UV light are that it can be used to kill bacteria and other microbes. It is commonly used to purify water for instance or clean things. UV light can also be used for a variety of other of application, such as black lights (which just look cool!). Also many compounds fluoresce (they emit light) when exposed to UV light. This is how forensic scientists can find traces of blood and other bodily fluids at crime scenes for instance. Finally exposure to some UV-B light causes the body to make Vitamin D, an important nutrient. While some exposure is important too much will cause sunburns and possibly cancer.
Ultra Violet Light was discovered by Johann Wilhelm Ritter in 1801.
Ultraviolet rays (as all electromagnetic waves with more energy then the visible spectrum) can be dangerous to humans. UV tyically just reacts with the skin to cause burns, th…rough prolonged exposure can cause mutations in the DNA of the skin, which causes skin cancer.
IR waves are longer than UV waves.
Light waves that are of slightly higher frequency than you can see.
