In the Rays of the Sun
Natural photograph of the waves of visible light from the sun
The sun is the only provide of natural, visible light. This light travels at 3 X 108 m/s, the speed of light. The visible light from the sun is the smallest section of the Electromagnetic Spectrum. These visible light waves are the middle in size and frequency of the Electromagnetic Spectrum. This light is what allows us to see all of our favorite colors. Isaac Newton invented the prism to visualize the colors. The different colors of the light are seen in different frequencies. The “cooler” colors have shorter wavelengths, while the warmer colors have longer wavelengths. The prism changes the “white light” into all these different frequencies. Water has the same ability as a prism, hence rainbows. The lens of my camera became a mini prism and mad little red circles, changing the frequency of the light. Parts of the sun’s rays are absorbed by the earth, and parts are reflected back into the sky. This photo is titled, In the Rays of the Sun, because the rays of the sun move our world. Quite simply, the main use of the sun’s rays is to be able to see things.
