What is color? Why do some objects look red, others green, still others blue?
Color is caused by (11) light rays. We see color because objects reflect light. Something that is red reflects (12) red light. It reflects a little green or blue light, too, but we do not see it. In the same way, a green object reflects mostly green light. White objects reflect (13) of light. Black objects do not reflect any light.
What happens to the colors of light that are not reflected? They are absorbed by the object. The (14) the color, the less light is reflected and the more light is absorbed. Light that is absorbed is (15) heat. For this reason, dark-colored clothes are warmer in the sunlight than lighter-colored clothes.
What is color? Why de some objects look red, others green, still others blue?
Color is caused by reflected light rays. We see color because objects reflect light. Something that is red reflects mostly red light. It reflects a little green or blue light, too, but we do not see it. In the same way, a green object reflects mostly green light. White objects reflect all colors of light. Black objects do not reflect any light.
What happens to the colors of light that are not reflected? They are absorbed by the object. The darker the color, the less light is reflected and the more light is absorbed. Light that is absorbed is turned into heat. For this reason, dark-colored clothes are warmer in the sunlight than lighter-colored clothes.
