How do you think is a rainbow made?

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.

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。
3 D; H2 u d! H: y7 n8 \; d3 y) g/ h/ u: n2 y: c) K: Z
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。
: @0 c6 Q( I! q% }
- W3 u3 r1 T" W$ Y' TSunlight 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 q5 x2 ?% l" K3 H
. \0 h2 u( m8 x, V) t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。8 F( P5 b& f5 S5 Z, ^
