O QUE SIGNIFICA GROUP SPEED EM INGLÊS
Velocidade grupal
A velocidade do grupo de uma onda é a velocidade com que a forma geral das amplitudes das ondas - conhecida como modulação ou envelope da onda - se propaga através do espaço. Por exemplo, imagine o que acontece se uma pedra é jogada no meio de uma lagoa muito imóvel. Quando a pedra atinge a superfície da água, aparece um padrão circular de ondas. Em breve se transforma em um anel circular de ondas com um centro quiescente. O anel de ondas em constante expansão é o grupo de ondas, dentro do qual se pode discernir ondulações individuais de diferentes comprimentos de onda que viajam a diferentes velocidades. As ondas mais longas viajam mais rápido do que o grupo como um todo, mas eles desaparecem quando se aproximam da vantagem. As ondas mais curtas viajam mais devagar e morrem quando emergem dos limites do grupo.
definição de group speed no dicionário inglês
A definição de velocidade do grupo no dicionário é a velocidade na qual a energia se propaga em uma onda. Esta é a quantidade determinada quando se mede a distância que a radiação viaja em um determinado momento. Em um meio em que a velocidade aumenta com o comprimento de onda, a velocidade do grupo é menor que a velocidade da fase e vice-versa.
