Ultraviolet light can be used to find minerals such as scheelite, which fluoresces bright blue under UV light. This fluorescence is helpful in mineral identification and exploration.
Ultraviolet light can be seen by bees, but not humans. Bees also cannot distinguish red from black.
The frequency of ultraviolet light with a wavelength of 300 nm can be calculated using the equation speed of light = frequency x wavelength. The speed of light is approximately 3.00 x 10^8 m/s. By rearranging the equation, we find that the frequency is around 1.00 x 10^15 Hz.
Ultraviolet radiation has a wavelength between 10 and 400 nanometers. The shorter the wavelength, the more energy each photon contains. To find the frequency, divide the speed of light (299,792,458 metets per second) by the wavelength.
A typical human eye will respond to wavelengths from about 390-750nm. In terms of frequency, this corresponds to a band in the vicinity of 400-790 THz. Bees and many other insects can see light in the ultraviolet, which helps them find nectar in flowers. Plant species that depend on insect pollination may owe reproductive success to their appearance in ultraviolet light, rather than how colorful they appear to humans. Birds too can see into the ultraviolet (300-400 nm), and some have sex-dependent markings on their plumage, which are only visible in the ultraviolet range. this is from the wikipedia article on visible light in the electromagnetic spectrum

UV refers to the "Ultraviolet". Do you mean the ultraviolet LED lights? Or the natural sun light? You could find details at Wikipedia.
Some insects use ultraviolet waves to find nectar. The ultraviolet light leaves marks on flowers, and the insects can sense them and find the nearby nectar.
UltraViolet
ultraviolet light can be used to find fingerprints and hidden blood
It can be used for helping insects find plants, and medical scanning.
Solar UV light is a type of ultraviolet (UV) radiation emitted by the sun. It is divided into three wavelength ranges: UVA, UVB, and UVC. UV light can have both positive and negative effects on human health, as it can cause sunburn and skin cancer, but also helps the body produce vitamin D.
There are many things you can use it for. If u have children can make a LED Christmas tree. Just type it into Google. Also ultraviolet LEDs are used to find scorpians as they light up under the light.
you could maybe go to a mine in Sud-bury..

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. Sunlight 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
Ultraviolet light is useful for many things from cool looking posters and party decorations to helping law enforcement find body fluids and evidence. Some government issued documents, like passports, have watermarks built in that can only bee seen under UV lights to check authenticity. Crime Scene Investigators can use UV lights to find blood that has been "cleaned" up, semen on surfaces, and other fluids that the suspect thought they wiped away. Many night clubs also use UV lights with invisible stamping to determine paying or underage customers. So the question maybe shouldn't be what can ultraviolet lights be used to find but rather what can they NOT find!
