LIGHT AND RAINBOW
 One of the most attractive phenomena of nature is
the Rainbow.
 It Occurs when the rays of sunlight pass through
raindrops. Passing white light through water droplets
it is divided into seven color lights.
 For white light becomes colored, it must pass
through a prism or a drop of water, change its
direction, as each one has their own direction.

 To see the color of everything that surrounds us,
it is necessary the daylight or that objects are lit
 All objects convey a sense of color. This is due to
the ability of their surfaces, on the one hand, to
absorb all or part of the white light that
illuminates, and secondly, to reflect the light of
the color that we can see.

 For that reason an egg is white. Because it
reflects all the white light and does not absorb
light.
 We can see a tomato red colored because it
absorbe all the colors of the white light but the
red, which is the color of the reflected light.

COLORED LIGHTS
 The colored lights can be obtained by decomposing
white light (by passing it through a prism or a drop
of water) or by using color filters (by placing a
transparent screen in a into a flashlight)
 If the white light can be decomposed into the colors
of the rainbow, you can also restore it. The white
light is achieved by mixing all the colored lights. But
it is not necessary to use all the rainbow to get it.
