Quotes About Photoelectric

Planck, a thoroughgoing conservative, had no taste for pursuing the radical consequences of his radiation formula. Someone else did: Albert Einstein. In a paper in 1905 that eventually won for him the Nobel Prize, Einstein connected Planck's idea of limited, discontinuous energy levels to the problem of the photoelectric effect.

Compton had in fact demonstrated in 1923 what Einstein had postulated in 1905 in his theory of the photoelectric effect: that light was wave but also simultaneously particle, photon.

Two phenomena in particular triggered the quantum revolution: the photoelectric effect and the structure of the atom.

Einstein would not, as it turned out, ever win a Nobel for his work on relativity and gravitation, nor for anything other than the photoelectric effect.

De hecho, fue precisamente por descubrir la ley del efecto fotoeléctrico por lo que se concedería a Einstein su único premio Nobel.

Einstein's theory produced a law of the photoelectric effect that was experimentally testable: the energy of emitted electrons would depend on the frequency of the light according to a simple mathematical formula involving Planck's constant.

In fact, it was specifically for discovering the law of the photoelectric effect that Einstein would win his only Nobel Prize.

What really transcends our understanding is the mechanism that permits these oscillations of abstract field quantities to carry energy. We know this is true; our relevant equations say so, and the solar energy collectors prove it. A photoelectric cell registers at this instant an energy that left the Sun, in the form of light, some eight minutes ago. Travelling across space, this light did not lose its energy; rather, it is part of the energetic excitations within empty space.
