 * 4.2 Refraction of light page 145**

Refraction is the changing of the direction of light. Whit light is made out of waves from different sizes. So, if that light is refracted, the wavelengths will all be different and make colours. The human eye can distinguish a wide range of colours, this happenes because of the different sizes and brightness of the colours. It comes into your eye and bounces off. That is why in dark, you cannot see any colour but black, because black isn't really defined a colour. no colour in dark. Primary Colours combine to make different colours so when 2 different colours come to your eye, it bounces and shows the secondary colours.
 * Questions || Answers ||
 * Define //Refraction.// || It is the bending or changing direction of a wave as it passes from one material to another. ||
 * What is a simpler word for //Refracted?// || Visible light. ||
 * Give an example of //Refraction.// || If a light wave is refracted, such as by passing through a prism, the different wavelenths bend by different amounts. ||
 * What is "white light"? || Sunlight. ||
 * Why does the light have colour when flowing through a prism? || Because the longer wavelengths are refracted less than the shorter wavelengths, different colours are separated when they emerge from the prism. ||
 * Name those colours. || Red, orange, yellow, green, blue, indigo, and violet. ||
