Rainbows are seen in the sky opposite the sun and are caused by the refraction ( bending of light ) and dispersion ( splitting up ) of sunlight in drops of rain or mist.

0 W, q, T# k* g彩虹出现在背对着太阳的天空中，因为太阳光通过雨或者雾的颗粒时会发生折射和分散，所以产生了彩虹。9 P* O6 b) S6 u# C) S

refraction 就是 “折射”，light bends as it passes through a transparent material for example, glass, prisms, rain drops. 当光线通过透明物质的时候（比如：玻璃、三棱镜、或者雨滴），它就会弯曲。这就是折射，refraction。
; o. W' t- y5 |% u: v" B1 `- x2 K O3 I" e l7 J5 [+ S% y
Sunlight hitting the rain or mist is dispersed into its constituent colours this is because the light is reflected at varying angles, creating a rainbow because the different colours refract and bend by different amounts. Each colour of the rainbow has a different wavelength.2 U! p ^: c/ B! M4 `. @1 {7 i
; `+ R* O' M, |4 y太阳光碰到了雨或者雾被分散成各种颜色。彩虹的每个颜色都有不同的波长，又因为光折射的角度不一样，所以形成了不同的颜色，因而创造了彩虹。
