Lab 5 Circular Motion & Gravity PHY250L EXPERIMENT 3: INVERSE SQUARE LAW Data Table Table 2. Distance vs. Light Data Distance from Wall (cm) Diameter of Light (cm) Area (cm?) 5 12 78.50 7 14 153.86 9 16 254.36 11 18 374.94 Post-Lab Questions 1. How did holding the light source at different distances from the wall change the area of light you saw? By increasing the space between the wall and the light source, the size of the illuminated area on the wall will expand. 2. What did you observe about the intensity (brightness) of the light at different distances? As the distance from the light source increases, the intensity of the light decreases 3. Make a plot of distance vs. intensity for the light shining from the cup to the wall (plot the intensity on the y-axis). Lab 5 Circular Motion & Gravity PHY250L Handwrite your name next to your graph. 4. Draw a line of best fit through your data points, and comment on the general shape of your plot, describing in words how the light intensity changes with distance Click here to enter text. 5. How does the area and intensity of the light in this experiment relate to the effects of gravity over increasing distance? Click here to enter text
