补充要求和说明：

1.To能够解释如何光电效应实验作品，为什么光的光子模式是需要解释的结果。
2.To学习强度的光对光电实验效果
3.To通过模拟估计普朗克常数，H
4.To被确定如何计算的光的波长，金属，或停止潜在的功函数，如果给定的其他两种。

通过给予负的电压电势至收集器，它需要更多的能量使电子以完成轴颈和启动电流。在该没有电子使其集电极被称为停止电位Vs，并可以用来确定最大动力学动能k具有通过使用以下等式电子电荷e（电子的最大值）的点：
K（最大）= EV5

它是显著要注意，漫游全部电子都会有这种能量，但将与一个范围基于金属的特性的能量的发射中使用。上述公式允许我们计算最大动能。喷出从表面的电子所需的最小能量被称为光电功函数。

爱因斯坦提出要注意的是辐射能量不continously分布在波前，而在小捆称为光子代替本地化。光子的。光子的能量将与它的频率有关，通过比例常数曾被称作普朗克常数，或elternately，使用波长（波长）和光速c的速度：
E = HF = HC /

制成钠的板开始时。保留所有的参数以外的光的颜色（波长）常数和显示的所有图形可用。

1.To be able explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results.
2.To study the effect of intensity of light on photoelectric experiment 
3.To estimate the Planck’s constant, h through the simulation
4.To be determine how to calculate the wavelength of light, the work function of the metal, or the stopping potential, if given other two.

To observe the photoelectric effect, you create a vacuum chamber with the photoconductive metal at one end a collector at the other . When a light shines on the metal, the electrons and released and move through the vacuum toward the collector. This creates a current in the wires connecting the two ends, which can be measured with an ammeter.

By administering a negative voltage potential to the collector, it takes more energy for the electrons to complete the journal and initiate the current. The point at which no electrons make it to the collector is called the stopping potential Vs, and can be used to determined the maximum kinetic energy k(max of the electrons) which have electronic charge e by using the following equation:
K(max)=ev5

It is significant to note that bot all of electrons will have this energy, but will be emitted with a range of energies based upon the the properties of the metal being used. The above equation allows us to calculate the maximum kinetic energy. The minimum energy required to eject an electron from the surface is called the photoelectric work function.

Einstein proposed to note that radiation energy is not continously distributed over the wavefront, but is instead localized in small bundles called photons. THe  photon’s. The photon’s energy would be associated with its frequency, through a proportionality constant knows as planck’s constant, or elternately, using the wavelength(lambda) and the speed of light c:
E=hf=hc/

Begining with the plate made of sodium. Keep all the parameters constant except for the colour (wavelength) of the light and display all the graph available.
