refraction

If water had a negative index of refraction, then a straw placed in a glass would appear to bend back under itself..如果水具有负折射率，那么放在玻璃杯中的吸管似乎可能弯曲到自身下方。

With all that reflection and refraction, modernism creates the illusion that there is an illusion when in fact it is a straightforward statement of money and power..通过反射和折射，现代主义创造了一个幻觉存在的假象，而实际上它是对金钱和权力不加掩饰的声明。

Rapidly changing refraction due to turbulence along the line of sight affects different colors of light by different amounts and generally produces a twinkling effect for stars..由于湍流而快速变化的折射在视线中会影响到光的不同颜色，这种影响也各不相同，一般会给恒星产生一种闪烁的效果。
