UV LIGHTING AND IT'S EFFECTS

There is a lot more to the universe than the light you and I can pick up with our eyes and brains. Although itís a shame that we canít see them naturally we can use technology to reveal the wavelengths of light normally invisible to us. Visible light is only part of the electromagnetic spectrum (a very small part) and I thought it would be interesting to see some familiar objects in unfamiliar ways.

The electromagnetic spectrum is usually split into seven parts: the radio, microwave, infrared, visible, ultraviolet, x-ray and gamma ray. You can find a good schematic of the EM spectrum over on Wikipedia. We obviously see things in the visible spectrum, but some things react like flowers and bees. They see some of the ultraviolet (one reason there are so many purple flowers). Here is a picture of a Geranium in the visible and then the UV. You can find more images like these, for all kinds of flowers over at http://www.naturfotograf.com/UV_flowers_list.html
