4.If your graph from part 3 is not linear,make a graph of Radiation Level versus 1/X2,using columns three and four from table 2.2. Questions 1.Which of the two graphs is more liner is it linear over the entire range of measurements? 2.The inverse square law states that the radiant energy per unit area emitted by a point source of radiation decreases as the square of the distance from the source to the point of detection.Does your data support this assertion? 3.Is the Stefan-Boltzmann Lamp truly a point source of radiation if not,how might this affect your results?Do you see such an effect in the data you have taken? 66 4.
