You set up an experiment with two polarizer screens on an optical bench and collect data for the intensity of the light at the detector as you vary the relative angle between the transmission axes of the polarizers. You create a plot of light intensity (in lux) vs cos2 θ with your data and get a linear fit for your graph gives a slope of 109.2 ± 1.144 and a y-intercept of 14.95 ± 1.141.
(a) What is intensity of the light source you used in your experiment? (with uncertainties)
