How good is the fit? Is this data linear over the entire range of distances? Comment on any discrepancies. What is the uncertainty on the slope? What intercept do you expect? Comment on these values and their uncertainties. \item Does radiation from the lamp follow the inverse square law? Can the lamp be considered a point source? If not, how could this affect your measurements? |
