Webb9 apr. 2024 · Discuss the particle model of light and the definition of photon Explain how and why the amount of light we see from an object depends upon its distance Coded … WebbThe light particle conceived by Einstein is called a photon. The main point of his light quantum theory is the idea that light's energy is related to its oscillation frequency (known as frequency in the case of radio waves). Oscillation frequency is equal to the speed of light divided by its wavelength.

WebbWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called … Although a photon is massless, it still has momentum. Einstein's E = mc^2 formula … For violet light, what's the energy of one violet photon? Well, the frequency of … Alright, so the bad news is that we cannot use P equals MV to find the momentum … Learn for free about math, art, computer programming, economics, physics, … Learn for free about math, art, computer programming, economics, physics, … Instead what we do is to use electrons. Since electrons have a rest mass, unlike … Webb18 mars 2024 · (A) The kinetic energy of any single emitted electron increases linearly with frequency above some threshold value (B) The electron kinetic energy is independent of the light intensity. (C) The number of electrons emitted per second (i.e. the electric current) is independent of frequency. real betis champions league

WebbWhen it does that, it's going to emit a photon. It's going to emit light. When the electron drops from a higher energy level to a lower energy level, it emits light. This is the process of emission. I could represent that photon here. This is how you usually see it in textbooks. We emit a photon, which is going to have a certain wavelength. WebbTo summarize, photons ARE particles that just show wave behaviour due to us having to describe them as wave functions due to uncertainty of their position. At least this is what I gather after reading QED from Feynman, but I won't pretend to understand anything (Neither did Feynman.) ( 22 votes) Upvote Flag Show more...
