Compare the slope of your Data Table 2 graph to the average wavelength (Ave, I) from Data Table 1 by calculating the % Difference. 5. For difficult measurements an error of 10% or less is acceptable; for most experiments an acceptable error is 5% or less. Reflecting on the lab, is the % Difference calculated for the wavelength in Data Table 2 within an acceptable % error? Explain why or why not?
