HOW RAINBOW FORMS

Rainbow Formation Dispersion of Light by Prisms Rainbow Formation Mirages One of nature's most splendid masterpieces is the rainbow. A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths , each associated with a distinct color. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye.

The net effect of the vast array of droplets is that a circular arc of ROYGBIV is seen across the sky. But just exactly how do the droplets of water disperse and reflect the light? And wh...

The problem is that dying might be easier than what follows a head injury. Volunteer at a neurological rehab hospital some day.   Helmets can't save you from every accident. Nothing can. But they can save you from a lot of accidents, maybe even most of them. If I had been wearing one on Dec. 2, 1988, I might not be taking anti-seizure pills every day, twice a day, for the rest of my life. If I had been hit by a t...
