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 120.2 ± 1.204 and
a y-intercept of 15.45 ± 2.141.
(a) What is intensity of the light source you used in your
experiment?
(b) What is ambient light in the room as you took your data?
