The document discusses the science of color and light. It explains that color is a sensation created in the brain from light stimuli. It describes how rainbows are formed when white light passes through raindrops and is separated into the colors of the visible spectrum. It also discusses how the color we see of objects depends on whether they absorb or reflect different wavelengths of light.

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.

LUCES DE COLORES
 Las luces de colores se pueden obtener descomponiendo la
luz blanca(haciéndola pasar por un prisma o gota de agua)
o tuilizando filtros de colores(poniendo una pantalla
transaparente de color en una linterna)
 Si la luz blanca se puede descomponer en los colores del
arcoiris, también es posible recomponerla. La luz blanca se
consigue mezclando todas las luces de colores. Pero no es
necesario utilizar todo el arcoiris para conseguirlo, como
veremos enseguida.
