Spelling Lesson 31:Proofreading

Proofreading

When light passes through a glass prism, it is bent, or refracted. Light of one specific wavelength, however, bends at one specific angle. Sunlight has a number of wavelengths, so when it passes through a prism, it separates into many angles. Forming a vivid band of colors. A rainbow is an arc of color that appears in the sky when sunlight passes through raindrops that act as a prism. Rainbows may look like physical objects you can touch, but they are an illusion - a temporary, if spectacular display of the sun's light. Trying to find the spot where a rainbow ends will forever elude those who search for it.


The real thing is in the book on page 128. I just corrected this on here.
