Transcript of Rainbows

Rainbows By:Ashley A rainbow is an optical phenomenon that is caused by reflection of light in water droplets in the Earth's atmosphere, resulting in a spectrum of light appearing in the sky. It takes the form of a multicolored arc also known as a bow, hence the name rainbow. The rainbow effect is also commonly seen near waterfalls or fountains. They can also be created through mist, spray and dew. It may be hard to interpret through the naked eye but some sources have stated that altogether there are about 100 color hues in the rainbow, but most people only see the 7 main colors; red, orange, yellow, green, blue, indigo and purple (violet). Pink is not usually a visible
color in the rainbow but it may
be included in the hues of the
rainbow. Double Rainbow Secondary rainbows are caused by a double reflection of sunlight inside the raindrops, because of this, the second rainbow's colors are switched so blue or violet are on the outside and red is on the inside. Twinned Rainbow A twinned rainbow is a rare event where two rainbow arcs start from a single base. Sometimes a double rainbow may occur at the same time as a twinned rainbow.

The reason for this has to do with the sun and rain, in winter the water droplets freeze into ice particles which do not produce a rainbow but may produce other interesting designs that have to do with light and reflection. Did You Know? *Did you know that two people are never seeing the exact same rainbow... *Did you know that when you are looking at a rainbow your right eye would be seeing a different image than the left... *Did you know rainbows are the world-wide symbol of peace and harmony... *Did you know rainbows appear to be arcs but they are actually circles... *Did you know that Sir Isaac Newton discovered the seven distinct colors that are visible in a rainbow... Rainbows have influenced many things
such as characters, movies, art, baking and music. http://en.wikipedia.org/wiki/Rainbow Info http://eo.ucar.edu/rainbows/ http://www.rainbowsuncatchers.com/facts_about_rainbows.htm Rainbow Dash https://www.google.ca/search?q=rainbow+dash&hl=en&tbm=isch&tbo=u&source=univ&sa=X&ei=okQ9UafMCoS-qgHovoH4DA&sqi=2&ved=0CDUQsAQ&biw=1440&bih=756#imgrc=nN1ysNS072LUuM%3A%3Bg-m8SYMY5upbUM%3Bhttp%253A%252F%252Fimages.wikia.com%252Fmlp%252Fimages%252Ff%252Ffb%252FCanterlot_Castle_Rainbow_Dash_3.png%3Bhttp%253A%252F%252Fmlp.wikia.com%252Fwiki%252FFile%253ACanterlot_Castle_Rainbow_Dash_3.png%3B2863%3B2574 Somewhere over the rainbow photo Rainbow film photo http://en.wikipedia.org/wiki/Over_the_Rainbow http://en.wikipedia.org/wiki/Rainbow_(1996_film) Rainbow cake Crayon art photo https://www.google.ca/search?q=rainbow+cake&hl=en&tbm=isch&tbo=u&source=univ&sa=X&ei=Xkc9UcGlCdTHqAG-84HIDg&ved=0CDsQsAQ&biw=1440&bih=756#imgrc=s2zWhegCk1AfuM%3A%3BKYVk3olMTVqITM%3Bhttp%253A%252F%252Fpixelatedcrumb.com%252Fwp-content%252Fuploads%252F2012%252F03%252Frainbow_cake-6.jpg%3Bhttp%253A%252F%252Fpixelatedcrumb.com%252F2012%252F03%252F25%252Frainbow-cake-and-a-giveaway%252F%3B3168%3B3168 https://www.google.ca/search?q=rainbow+artwork&hl=en&tbm=isch&tbo=u&source=univ&sa=X&ei=i0c9UYvNHcGSqQGx3IH4DQ&ved=0CC8QsAQ&biw=1440&bih=756#imgrc=-RgGJ6auoxf7hM%3A%3Buq75smRjPyMZXM%3Bhttp%253A%252F%252F4.bp.blogspot.com%252F-IRd7AsznM-E%252FTm1ylG24HaI%252FAAAAAAAAAHU%252FWktZ9YP1a-w%252Fs1600%252Fblog%252Brainbow.bmp%3Bhttp%253A%252F%252Flittleteetee.blogspot.com%252F2011%252F09%252Fdiy-rainbow-artwork.html%3B700%3B542 THE END!!
