You should justify all of your answers for full credit. You pass light from a hydrogen lamp (as opposed to the mercury lamp from our class) through a diffraction grating to separate it into its component wavelengths. You then shine the light on a silicon surface to examine the photoelectric effect for aluminum in the hopes of making an inexpensive photocell. You find the following data: Color ...Physics: The Photoelectric Effect

Photoelectric Effect Worksheet The photoelectric effect refers to the emission of electrons from metallic surfaces usually caused by incident light. The incident light is absorbed by electrons thus giving them sufficient energy to break from the metallic surface. It is a phenomenon that was explained by Albert Einstein, and he received a Noble Peace prize for it in 1921. Evidence of the ...Photoelectic Effect Lesson: Project Homepage
The photoelectric effect happens when particles of light, called photons, hit a metal. Electrons hanging on to the outside of the metal can get knocked off if the photons hit them hard enough (that is, with enough energy). In this way, the photoelectric effect turns the energy of light shining on a material into an electrical current that can light a light bulb or drive a car.AS Phys 1: Worksheet -Introduction to the Photoelectric Effect

This DLO is a virtual reproduction of Millikan's photoelectric experiment. Use either the input box or the slider bar to adjust the wavelength of incoming photons. Adjust the photon density slider to change the photon density or the number of photons of incoming light. The Voltage slider will create an electric field to oppose the electrons' motion. The Record Data button will record the ...Concept Questions for the Photoelectric Effect with ...
Compton effect was observed and explained by Arthur Compton. In the photoelectric effect, the entire energy of the incident photon is acquired by a single electron but, in the Compton effect, the incident photon transfers only a part of its energy to an electron. The photoelectric effect is a low energy phenomenon, and the interacted photons disappear just after they deliver their energy to ...Photoelectric effect | physics | Britannica

Here is the last photoelectric effect question to appear as a free response question. It was asked in 2000 as the fifth of seven questions. It was worth 10 points. They’ve asked about everything else in the intervening 8 tests, so it might be time for Einstein to make a comeback. Try it out, and check your answers. 2000 Question 5 (10 points) A sodium photoelectric surface with work function ...Chapter Notes: Photoelectric Effect Physics Class 12 ...
The photoelectric effect occurs when light of high enough energy strikes an object. When light strikes the object it emits electrons. Now whether electrons are emitted or not depends entirely on the energy of the light and not the intensity of the light. What this simply means is that it does not matter if the light is bright or dim. What matters is the color (and hence the frequency) of the ...What is applications of photoelectric effect in ... - Answers

Photoelectric effect is the emission of electrons when electromagnetic radiations having sufficient frequency incident on certain metal surfaces. We call the emitted electrons as photoelectrons and the current they constitute as photocurrent. The phenomenon was first observed by Heinrich Hertz in 1880 and explained by Albert Einstein in 1905 using Max Planck's quantum theory of light. As the ...Photoelectric Effect Lab - The Physics Aviary
