A lot of insects with multifaceted eyes use U.V. to navigate with. Even if the sun is obscured by clouds U.V. rays come through. Using a built-in method the insect can tell the angle of the sun to the horizon and get around. Most flowers look totally different to an insect. The flower radiates reflected UV to attract bugs for pollination.

Does the moon effect life on earth?
Yes, it causes the tides which affect sea currents and nocturnal creatures use its light.
How do you use the words ultraviolet rays in a sentence?
Too much exposure to the ultraviolet rays from the Sun can prove to be fatal.
What Layers of the Sun can be seen with some type of telescope?
DO NOT LOOK AT THE SUN WITH A CONVENTIONAL TELESCOPE. Doing so can cause massive eye damage and blindness. Theoretically only the photosphere would be visible anyway.Scientists can use special telescopes (such as ultraviolet telescopes) to see other parts of the sun (such as the corona).
What can you use to see round corners?
a mirror or some thing that reflects light
What is the difference between Infrared and visible satellite images?
Electromagnetic (EM) radiation is the word we use for any sort of energy wave that propagates through space. We can measure the frequency of the wave, or the wavelength. The speed of light is 186,000 miles per second, which is about 300,000,000 meters per second. We can use this to convert frequency to wavelength; the frequency (in Hertz) times the wavelength (in meters) equals the speed of light. The EM spectrum includes radio, microwaves, heat, light, X-rays and gamma rays; it is all electromagnetic radiation, and the only difference is the frequency (or wavelength). So heat rays are part of the EM spectrum that is just below the red color of light, so "infra-" (below) red; infrared. Infrared (IR) is light that is a frequency a little below what our eyes can see, just as ultraviolet (UV) rays are just light that's a little higher in frequency than our eyes see. We see when light is reflected back to our eyes. When light hits vegetation, it reflects best in the IR range, so satellite photos in the IR range can see tiny changes in the way we see plants.
What are examples of bioluminescence?
Plankton (collective name for microscopic sea creatures) - wave your hand through sea water at night, and you will see the plankton flouresce briefly as they expire. Fireflies Scorpions - though their luminescence can only be seen under ultraviolet light - the reason for it is unknown, as they cannot see in the ultraviolet spectrum themselves.
What property of waves let us see things which don't emit light?
Our eyes can only see visible light. We can use other technologies such as infrared or ultraviolet sensors, but these use electronics to convert them back into visible light that we can see when they are displayed on the monitor. Sometimes we think we can see infrared radiation or ultraviolet light with our own eyes, but in reality those sources are emitting a small amount of visible light since they are so close to the visible light spectrum.
What are use of ultraviolet light?
you can use ultraviolet in bug zappers, identifying money, in sun beds and many others:
How do you use the word ultraviolet in a sentence?
Ultraviolet is a type of electromagnetic radiation. It has a higher frequency than visible light. It is called ultraviolet because violet light has the highest energy of the colours. UV light has more energy, and hence ultraviolet.
How many people does ultraviolet light effect per year?
Every single person. Our bodies use ultraviolet light in the creation of certain vitamins.
Is ultraviolet a source of light?
Yes U.V. rays are a source of light they are what we use sunscreen for
How does ultraviolet light work on scorpions?
They just use a harsher light in the electromagnetic spectrum.
How would you use ultraviolet in a sentence?
The ultraviolet light of the sun will give you good color, but too much exposure can be dangerous.
What type of light can the hubble telescope use to see the images?
The instruments on board of the HST are sensitive to ultraviolet through infrared (115 to 2500 nanometers.
Can deep sea creatures see in the dark?
After just a few hundred metres there is very little light. Most deep sea creatures have very large eyes that can detect any light that is available. Even though there is virtually no light coming from the surface lots of deep sea creatures produce light through a process called bioluminescence. It is useful to be able to see this light as if you eat the light, you will be eating the creature that it is attached to. Unfortunately some creatures use these lights to draw in their own dinner!
What do you use uv light for?
Ultraviolet light comes from the sun, and is what makes our skin darker, so we use UV light to tan ourselves in tanning salons.
Are ultraviolet rays violet in color?
Our eyes can't see ultraviolet light, so it has no color. The highest frequency our eyes can see is violet, and ultraviolet is above that frequency. The name ultraviolet just means "above violet."
