Aware(知道) that the electromagnetic theory of light failed to explain the photoelectric effect(光电效应), Albert Einstein in 1905 sough(寻找)t some other way of understanding it.相关知识点: 试题来源: 解析 爱因斯坦由于清楚地知道光的电磁理论不能解释光电效应,所以他于1905年寻找到了另外一种方法来...
量子力学:从电磁场理解光电效应Quantum Mechanics:Explain Photoelectric Effect by Electromagnetic Field 0.前言 对于光电效应的普遍解释是其证明了光的粒子性(量子性)。但是由于光具有波粒二象性,那么自然可以直接将光看作普通的电磁波,并将电子进行量子化,直接越过光子的概念解释光电效应。 本文基于威利斯兰姆(Willis L...
This course focuses on applications from engineering point of view, explain the photoelectric effect and various optical phenomena, describes the structure, principles of common light sources and Photodetectors, focuses the photodiode, CCD and other parameters and scope of use of the device. ...
Then Einstein explained this phenomenon with respect to the quantum perspective. The first classical electromagnetic field and staccato stated the failure to mention it to explain the photoelectric effect of Einstein's views on pay and eventually all of the photoelectric effect, Compton scattering and ...
14 (a)Explain what is meant by the work function of a metal.*(b) Observations of the photoelectric effect support the particle theory of light.State one such observation and explain how it supports the particle theory of light. 相关知识点: ...
The photons passed their energy in fixed quantities to atoms inside the metal, knocking some of their electrons out of them, so producing an electric current. Artwork: The photoelectric effect: When photons of light (left) hit a sheet of metal, they pass their energy to electrons (orange) ...
The more light that shines, the more electrons jump up and the more current flows.This is what we mean by photovoltaic—light making voltage—and it's one kind of what scientists call the photoelectric effect.How do solar cells work? Artwork: How a simple, single-junction solar cell works...

4. Conclusion: Therefore, the work function is a critical parameter in the photoelectric effect, as it determines the threshold energy needed for photoemission of electrons from the metal. Part (ii): Calculation of Maximum Wavelength 1. Energy-Wavelength Relationship: The energy (E) of a photon...
How does one explain the emission of electron from a photosensitive surface with te help of Einstein's photoelectric equation ? View Solution If the threshold wavelength(λ0)for ejection of electron from metal is350nmthen work function for the photoelectric emission is ...
