Question

5) You bought a set of lawn chairs at Wally Land for your presidential election party. These are those painted aluminum chairs with the woven Nylon seats and backs. Two thirds of the chairs were red and one third were purple (blue really, but the political angle works better with purple).   You set them out on your deck in Casa Grande in January and in October, while you were out shooting at some endangered species flying over your property, you noticed that the red chairs were now gray in color. The Blue ones still looked new, dangitall. Explain why the red chairs faded in color, yet the blue ones did not. And it had nothing to do with politics ?

Answer the question in clear words and in very good description!!! Please type your answer. Thanks

Explanation / Answer

The red chairs turns to grey due to photodegradation. Photodegradation is the process of fading of colors by absorbing light. The colors we see are based upon the chemical bonds and the amount of light that is absorbed in a particular wavelength.

Red color absorbs UV light more compared to blue. Ultraviolet rays can break down the chemical bonds and thus fade the color(s) in an object. Since the red color absorbs UV rays more, so it fades to grey while the blue remains the same.
