| Abstract: | Based on microprocessor control unit,the photoelectric effect demonstration instrument was designed.By adjusting the light,the instrument could demonstrate the changes of the current of photoelectric tube,the resistance of photo-resistance and the voltage of photocell with the illumination intensity simultaneously;it could also show the relationship of photo-electronic emission and the incident light's frequency with the change of illumination type. |
