Colors
Color adds beauty to our lives
understanding colors involves: physics, chemistry, physiology and psychology
Visible light is an electromagnetic wave with frequencies between: 1014-1016 Hz
The color of the light is determined by the frequencies of the light rays entering our eyes
the colors we perceive from objects are determined by two factors: the color present in the illuminating light and the colors reflected by the object
Different frequency light rays are interpreted in different ways by our brain, creating the sensation of colors
brain has an additive effect: different frequency light rays combine in our eyes, and create sensation of new colors
a combination of light beams that produces most of the colors: red, green and blue
complimentary colors: combined produce white
why the Sun is yellow and the sky blue?
