WebbIllustration Credit. Einstein noted that careful experiments involving the photoelectric effect could show whether light consistes of particles or waves. In 1887, German physicist Heinrich Hertz noticed that shining a beam of ultraviolet light onto a metal plate could cause it to shoot sparks. It wasn't the emission that was surprising. WebbThe photoelectric effect is the process that involves the ejection or release of electrons from the surface of materials (generally a metal) when light falls on them.

Webb2 dec. 1999 · The motivation for the Nobel Prize to Einstein in 1922 was based on his discovery of the law of the photoelectric effect. Albert Einstein Einstein repeated the statistical calculation with Planck’s formula as the basis, which is more general than Wien’s, and drew the conclusion that both the concept of waves and the concept of … WebbThe photoelectric effect shows that light behaves like a photon or a particle packed with energy, in other words light waves behave like particles. Figure 2 According to Particle theory of light, light energy will increase to a discreet and finite value unless λ goes to zero, which will never happen according to the Particle in a One-Dimensional Box theory. WebbAlthough a photon is massless, it still has momentum. Einstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a ... how do you find base
