摘 要:基于Visual C++语言对光电效应实验进行了计算机仿真.该仿真实验能够实现如下功能:(1)可以调整入射光强度、入射光波长(频率)、极板间电压大小,并及时给出实验结果的变化;(2)可以正确演示光电效应的基本规律;(3)可以显示光电流与电压之间、光电流与光强度之间以及光电子最大初动能与光频率之间的关系曲线;(4)提供该仿真程序的主要源代码,并鼓励学生去修改、完善、演示该仿真实验.Based on Visual C + +, a computer simulation were designed for photoelectric effect experiment. The following functions can be achieved by the simulation experiment, (1) The simulation allows students to control inputs which include light intensity, wavelength (frequency), and voltage, and to receive immediate feedback on the results of changes; (2) The simulation is able to correctly predict the results of photoelectric effect experiments; (3) The simulation can show relationship between current vs. voltage, and current vs. intensity, and electronkinetic energy vs. frequency on graphs; (4) The main source code of simulation are provided. Students are welcomed to modify, improve the program, and demonstrate the simulation experiment.
