O QUE SIGNIFICA REFRACTION EM INGLÊS
Refração
A refração é a mudança na direção de uma onda devido a uma mudança em seu meio de transmissão. A refração é essencialmente um fenômeno superficial. O fenômeno é principalmente em governança para a lei de conservação de energia e impulso. Devido à mudança de média, a velocidade da fase da onda é alterada, mas sua freqüência permanece constante. Isto é mais comum observado quando uma onda passa de um meio para outro em qualquer ângulo diferente de 90 ° ou 0 °. A refração da luz é o fenômeno mais comumente observado, mas qualquer tipo de onda pode refrear quando interage com um meio, por exemplo, quando as ondas sonoras passam de um meio para outro ou quando as ondas de água se movem para a água de uma profundidade diferente. A refração é descrita pela lei de Snell, que afirma que para um dado par de meios e uma onda com uma única freqüência, a proporção dos senos do ângulo de incidência θ1 e ângulo de refração θ2 é equivalente à proporção de velocidades de fase na dois meios de comunicação, ou ...
definição de refraction no dicionário inglês
A primeira definição de refração no dicionário é a mudança na direção de uma onda de propagação, como luz ou som, passando de um meio para outro em que ele tenha uma velocidade diferente. Outra definição de refração é a quantidade pela qual uma onda é refratada. A refração também é a capacidade do olho para refractar a luz.

2 CITAÇÕES EM INGLÊS COM «REFRACTION»
Citações e frases célebres com a palavra
refraction.
The model I came up with in 1964 is just the invention of a rather strange sort of medium that looks the same in all directions and produces a kind of refraction that is a little bit more complicated than that of light in glass or water.
Similarly, many a young man, hearing for the first time of the refraction of stellar light, has thought that doubt was cast on the whole of astronomy, whereas nothing is required but an easily effected and unimportant correction to put everything right again.
