You may have polarized sunglasses that eliminate glare by polarizing the light. When light is polarized, all of the waves are
traveling in parallel planes Suppose vertically polarized light with intensity lo strikes a polarized filter with its axis at an angle
If is 45°, write
ofo with the vertical. The intensity of the transmitted light, and
are related by the equation Co:
10
as a function of

Step-by-step explanation:

For polarized light, the intensity of the light transmitted through a polarizer filter is given by Malus' Law:

where:

is the original intensity of the light before the filter

is the intensity of the light after the filter

is the angle between the direction of polarization of the light and the direction of the axis of the polarizer filter

In this problem, we have:

is the initial intensity of the polarized light

is the angle between the axis of the filter and the direction of polarization of the light

Substituting, we find the intensity of the transmitted light:
