WitrynaFirst the intensity is reduced as you write above. (For unpolarized light incident on a polarizer you average over all possible polarization and get I = I u p / 2 .) Second, the light that passes now has the polarization of the filter it just passed. The second effect is what makes the trick work.

Because the light appears to come from above, the visual system infers that the upper square is receiving more incident light than lower square. Because the two gray patches have the same physical intensity, the upper one must be less reflective than lower one.

Like other SI base units, the candela has an operational definition—it is defined by the description of a physical process that will produce one candela of luminous intensity. By definition, if one constructs a light source that emits monochromatic green light with a frequency of 540 THz, and that has a radiant intensity of 1/683 watts per steradian in a given direction, that light source will emit one candela in the specified direction.
