PhotoElectric Effect Simulator for Android

11 things about PhotoElectric Effect Simulator

1. To make sense of the fact that light can eject electrons even if its intensity is low, Albert Einstein proposed that a beam of light is not a wave propagating through space, but rather a collection of discrete wave packets (photons), each with energy hf.

2. n 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as the result of light energy being carried in discrete quantized packets.

3. My sincere gratitude for the significant contributions of Francisco Esquembre, Fu-Kwun Hwang, Wolfgang Christian, Félix Jesús Garcia Clemente, Anne Cox, Andrew Duffy, Todd Timberlake and many more in the Open Source Physics community.

4. The photoelectric effect or photoemission (given by Albert Einstein) is the production of electrons or other free carriers when light is shone onto a material.

5. This shed light on Max Planck's previous discovery of the Planck relation (E = hf) linking energy (E) and frequency (f) as arising from quantization of energy.

6. An open source physics at Singapore simulation based on codes written by Fu-Kwun Hwang, Loo Kang WEE, Tze Kwang Leong.

7. Below that threshold, no electrons are emitted from the metal regardless of the light intensity or the length of time of exposure to the light.

8. Electrons are dislodged only by the impingement of photons when those photons reach or exceed a threshold frequency (energy).

9. This simulation has been customised for A level Physics education, and it is an open source project.

10. In 1914, Robert Millikan's experiment confirmed Einstein's law on photoelectric effect.

11. Electrons emitted in this manner can be called photoelectrons.
