So Einstein proposed that these light quanta were, in fact, real particles that could account for a few reasons and unexplained experiments having to do with knocking electrons off of metals and gas molecules. He turned out to be right on all counts, and got a Nobel Prize for his work. But that's a story for another day. Learn about Albert ...
Mar 12, 2024 · Suppose someone reading his 1905 paper wanted to interpret it by saying that Einstein's so-called particles of light are simply short wave-trains that only occupy a small region of space. Comparing the wavelength of visible light (a few hundred nm) to the size of an atom (on the order of 0.1 nm), explain why this poses a difficulty for reconciling the particle and wave theories.
Mar 17, 2005 · In the face of this universally held knowledge, Einstein proposed that light was not a continuous wave, but consisted of localized particles. As Einstein wrote in the introduction to his March ...
Einstein realized that all of these “surprises” were not surprising at all if you considered light to be a stream of particles, termed photons. In Einstein’s model of light, light is a stream of photons where the energy of each individual photon is directly proportional to its frequency. Ephoton = hf (4.1.1) (4.1.1) E p h o t o n = h f.
Nov 5, 2017 · For Einstein, the solution was clear. He proposed that light consists of light quanta. In other words, light is made up of particles that have an energy, which today we call photons. Therefore ...
Sep 7, 2017 · Einstein then postulated that the light comes in little packets of energy where the brighter the light, the more packets, but the individual light packets (photons) have the same energy. If the frequency is too low, the light photons have less energy then the binding energy of the surface electrons to the metal and no electrons will be freed from the plate, no matter how many packets you throw ...

First, he began by shining ultraviolet light on the surface of a metal. When he did this, he was able to detect electrons being emitted from the surface. This was Einstein's explanation: If the energy in light comes in bundles, then one can think of light as containing tiny lumps, or photons. When these photons strike a metal surface, they act ...
