O QUE SIGNIFICA PHOTOELECTRICITY EM INGLÊS

Efeito fotoelétrico

Photoelectric effect

O efeito fotoelétrico é a observação de que muitos metais emitem elétrons quando a luz brilha sobre eles. Os elétrons emitidos dessa maneira podem ser chamados de fotoeletrônicos. De acordo com a teoria eletromagnética clássica, esse efeito pode ser atribuído à transferência de energia da luz para um elétron no metal. Nesta perspectiva, uma alteração na amplitude ou comprimento de onda da luz induziria mudanças na taxa de emissão de elétrons do metal. Além disso, de acordo com esta teoria, espera-se que uma luz suficientemente fraca mostre um tempo de latência entre o brilho inicial da sua luz e a subsequente emissão de um elétron. No entanto, os resultados experimentais não se correlacionaram com nenhuma das duas previsões feitas por essa teoria. Em vez disso, como se verifica, os elétrons são apenas desalojados pelo efeito fotoelétrico se a luz atingir ou exceder uma freqüência de limiar, abaixo da qual nenhum elétron pode ser emitido pelo metal, independentemente da amplitude e tempo de exposição temporal da luz.

The photoelectric effect is the observation that many metals emit electrons when light shines upon them. Electrons emitted in this manner may be called photoelectrons. According to classical electromagnetic theory, this effect can be attributed to the transfer of energy from the light to an electron in the metal. From this perspective, an alteration in either the amplitude or wavelength of light would induce changes in the rate of emission of electrons from the metal. Furthermore, according to this theory, a sufficiently dim light would be expected to show a lag time between the initial shining of its light and the subsequent emission of an electron. However, the experimental results did not correlate with either of the two predictions made by this theory. Instead, as it turns out, electrons are only dislodged by the photoelectric effect if light reaches or exceeds a threshold frequency, below which no electrons can be emitted from the metal regardless of the amplitude and temporal length of exposure of light.
