摘要
研究用电脑控制光强与距离关系的实验中,用光强传感器测量光的照度,电脑软件采集光照度与距离的数据,用Origin7.0软件处理实验数据,得到受光物体的照度与距离的平方成反比。
This paper use the computer to control the intensity and distance relation experiments, using light intensity sensor for measuring light intensity, computer software to capture light intensity and distance data,using Origin7.0 software to process the experimental data,obtained by linear fitting of straight line equation, so as to obtain the intensity and distance square countdown presents nearly proportional relationship. So light object illumination and inversely proportional to the square of the distance.
