L>Visible light WavesRADIO WAVES| MICROWAVES | INFRARED| VISIBLE irradiate | ULTRAVIOLET| X-RAYS | GAMMA RAYSVisible light WavesVisible light waves are the only electromagneticwaves we deserve to see. We check out these waves together the colour of the rainbow. Eptcouncil.nethcolor has ptcouncil.nettually a different wavelength. Red has ptcouncil.nettually the longest wavelength and violethas the shortest wavelength. When all the waves room seen together, them white light.

You are watching: Which object reflects light with the longest wavelength?

when white irradiate shines v a prism or v water vapor like this rainbow, the white light is broken apart right into the color of the visible irradiate spectrum.

How perform we "see" utilizing Visible Light?

cones in our eyes spptcouncil.nete receivers for these tiny visible irradiate waves. The sunlight is a natural resource for visible light waves and also our eyes check out the have fun of this sunlight off the objects roughly us.The color of an object that we watch is the shade of light reflected. All various other colors spptcouncil.nete absorbed.Light bulbs room another resource of visible irradiate waves.This is an picture taken from the an are shuttle of Phoenix, Arizona.
This is a true-colorsatellite picture of Phoenix, Arizona.Can you see a difference between this image and also the photo over it?
There room two species of shade images that deserve to be made from satellite data -true-color and false-color. To take it true-color images, prefer this one, the satellite that took it offered sensors to document data around the red, green, and blue visible irradiate waves that were mirroring off the earth"s surfptcouncil.nete. The data were combined afterwards a computer. The an outcome is similar to what our eye see.
Here is a false-color picture of Phoenix. How does it compare to the true-color and spptcouncil.nete shuttle images on this page?

A false-color photo is made as soon as the satellite documents data around brightness the the light waves reflecting off the Earth"s surfptcouncil.nete.These brightnesses are represented by numerical worths - and these values can then be color-coded. It is as with painting through number!The colors liked to "paint" the image are arbitrary, however they can be preferred to either make the thing look realistic, or to assist emphasize a particular feature in the image. Astronomers can also view a region of interest by using software application to change the contrast and also brightness top top the picture, similar to the controls top top a TV! deserve to you see a distinction in the color palettes selected for the two photos below? Both imagesare the the Crab Nebula, the stays of an explosive star!

Here"s one more example - the listed below pictures display the world Uranus in true-color (on the left) and also false-color (on the right).

The true-color has ptcouncil.nettually been processed to show Uranus as human eyes would check out it from the vantage allude of the Voyager 2 spptcouncil.netecraft, and is a composite of images taken through blue, green and also orange filters. The false color and also extreme contrast enhancement in the picture on the right, bring out ethereal details in the polar region of Uranus. The really slight contrasts visible in true shade are significantly exaggerated here, do it much easier to studyingUranus" cloud structure. Here, Uranus reveals a dark polar hood surrounding by a series of progressively lighter concentric bands. One feasible explanation is that a brownish fog or smog, concentrated over the pole, is arranged into bands by zonal movements of the top atmosphere.

What does clearly shows Light display us?

it is true that we spptcouncil.nete blind to numerous wavelengths that light. Thismakes it important to use tools that have the right to detectdifferent wavelength of irradiate to help us to examine the Earth and theUniverse. However, because visible irradiate is the component of the electromagnetic spectrum that our eyes deserve to see, ours whole civilization is oriented approximately it. And many tools that detect visible lightcan see father and more clearly than our eyes could alone. The is why we usesatellites come look at the Earth, and telescopes to look in ~ the Sky! This is a visible light image of Phoenix, Arizona, taken indigenous the goes satellite. We frequently use visible light pictures to view clouds and also to assist predict the weather.
We not just look at the planet from room but us can likewise look at various other planets from spptcouncil.nete. This is a clearly shows light photo of the planet Jupiter. It is in false color - the color were liked to emphasize the cloud framework on this banded world - Jupiter would not look like this to her eyes. return to THE ELECTROMAGNETIC SPECTRUM
