The intensity of linearly polarized light transmitted through a linear polarizer is governed by the angle between the light's polarization and the polarizer's axis, as described by Malus's Law.

states that the intensity of linearly
polarized light that passes through a
perfect linear polarizer is directly
related to the angle between the light's
initial polarization and the axis of the polarizer
polarizer
for example have you ever placed two
linear polarizers in a beam of light and
rotated the polarizers relative to each
other if the polarizers start out with
their axes aligned and you rotate the
second polarizer you'll notice that the
light dims before completely
disappearing then becomes bright again
this change in intensity can be
calculated using malice's law and is
given by the equation I equals I naught
times the cosine squared of theta I
where I naught is the initial intensity
of the input beam to the second
polarizer and Theta I is the angle
between the axis of the polarizer and
