In the laws of optics experiment, a student measured the intensity of a light source at different distances with respect to the light source using a light probe. The following table shows the data collected in this experiment.
r (m) | I (Lux) |
0.050 | 636.6 |
0.100 | 159.2 |
0.150 | 70.7 |
0.200 | 39.8 |
0.250 | 25.5 |
0.300 | 17.7 |
0.350 | 13.0 |
0.400 | 9.9 |
0.450 | 7.9 |
0.500 | 6.4 |
