光的色散(Dispersion of light)指的是复色光分解为单色光的现象.牛顿在1666年最先利用三棱镜观察到光的色散,把白色的太阳光分解为红、橙、黄、绿、蓝、靛、紫七种色光,从而让人们认识到白色的太阳光是由多种色光组成的.1.设计并进行三棱镜实验牛顿从笛卡儿的棱镜实验得到启发,又借鉴胡克和玻意耳的分光实验:胡克用一只充满水的烧瓶代替棱镜,光屏距离折
Dispersion of light refers to the phenomenon of the complex color light decomposing into monochromatic light.Newton first observed the dispersion of light by a prism in 1666 and decomposed the white sunlight into red, orange, yellow, green, Blue, indigo, purple seven kinds of color light, so that people realize that the white sun is composed of a variety of color light .1. Design and conduct prism experiments Newton from Cartesian prism experiment inspired, but also learn from Hook and glassy Ear splitting experiment: Hook uses a water-filled flask instead of a prism, with the screen off
