refraction of sth
The refraction of light through a prism produces a spectrum.
光通过棱镜的折射产生光谱。
折射
折射程度；耐热性；耐火性；波(如光波或声波)从一种介质进入另一种光学密度不同的介质时发生的偏转或弯曲。；波(光或声)从一种介质进入另一种介质时方向的改变；金属或化合物耐热的程度。
the bending of a wave, such as light or sound, as it passes from one medium to another
波(如光波或声波)从一种介质进入另一种光学密度不同的介质时发生的偏转或弯曲。
The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density.
波(光或声)从一种介质进入另一种介质时方向的改变
the change in direction of a propagating wave (light or sound) when passing from one medium to another
金属或化合物耐热的程度。
The degree to which a metal or compound can withstand heat
传播波的弯曲量
the amount by which a propagating wave is bent
The prism demonstrates the refraction of light into a spectrum.
三棱镜展示了光折射成光谱的现象。
用法提示：refraction 作为名词，表示光线的折射现象。
Sound waves undergo refraction when passing through layers of air at different temperatures.
声波穿过不同温度的空气层时会发生折射。
用法提示：refraction 指声波的折射，这里用作不可数名词。
Optical lenses correct vision by controlling the refraction of incoming light.
光学镜片通过控制入射光的折射来矫正视力。
用法提示：refraction 表示光线的折射，是句中的核心概念。
The refraction of light through a prism produces a spectrum.
光通过棱镜的折射产生光谱。
Sound waves undergo refraction when passing through layers of air at different temperatures.
声波在经过不同温度的空气层时发生折射。
Refraction occurs at the boundary between two media.
折射发生在两种介质的边界处。
日常英语中常用，但不如 refraction 精确；refraction 特指波穿过介质边界时因波速改变而发生的偏转，bending 可泛指任何弯曲。
强调方向改变，但可指任何原因（如磁场、障碍物）引起的偏斜；若语境强调波速变化导致的折射，用 deflection 不够严谨。
口语中可说 the turning of the light，但语义笼统，不专指波在介质界面的弯曲，正式物理语境应使用 refraction。
grammar · medium
易错句子I saw my face in the water due to refraction.
正确表达I saw my face in the water due to reflection.
汉语中'折射'和'反射'容易混淆，'refraction'指光线穿过不同介质时方向改变，'reflection'指光线从表面弹回。这里描述的是镜像，应使用'reflection'。
grammar · medium
易错句子There are many refraction in this prism.
正确表达There are many refractions in this prism.
'refraction'是可数名词，表示具体的折射现象时应用复数形式'refractions'，错误地省略了-s。
reflection是光线返回原介质，refraction是光线进入另一介质时方向改变
diffraction是波遇到障碍物时弯曲，refraction是波通过界面时方向改变
折射角
The angle of refraction depends on the optical densities of the two media.
折射角取决于两种介质的光学密度。
折射率
Water has a higher index of refraction than air.
水的折射率高于空气。
光的折射
The refraction of light through a prism creates a spectrum.
光通过棱镜的折射产生光谱。
大气折射
Atmospheric refraction makes the sun visible before it actually rises.
大气折射使太阳在真正升起前就可见。
声波的折射
The refraction of sound explains why distant noises can be heard at night.
声波的折射解释了为什么夜间能听到远处的声音。
