What is color? Why do some objects look red, others green, others blue?
Color is caused by reflected light rays. We see color because objects reflect light. Some thing that is red reflects mostly red light. 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 light-colored clothes.
In the sunlight, the coolest clothes would be ______.
选项
A、yellow
B、black
C、green
D、white
答案
D
解析
通过第三段最后两句话,可知颜色越深,吸收的光就越多,因此穿深颜色的衣服比穿浅颜色的衣服暖和。该题问的是最冷的衣服颜色,应该选D。
