intensity of light through polarizer equation

When linearly the polarised light basically travels through a second polarizer (analyzer), its polarizing axis creates an angle (d) with the first polarizer's polarizing axis.Regardless of how the polarising axis is oriented, when unpolarized light is incident on a perfect polarizer, the intensity of the transmitted light is generally precisely half that of the incident unpolarized light.The law basically allows us to verify the nature of polarised light statistically. When polarized light of intensity I is incident on a polarizer, the transmitted intensity is given by I I, where is the angle between the polarization direction of the incident light and the axis of the filter.In the situation shown, the transmitted intensity can be calculated by applying the Law of Malus twice. Generally you should expect fields to have three vector components, e.g. At right above, a third sheet of polaroid is inserted between the crossed polarizers. According to Malus' law, the intensity of plane-polarized light passing through an analyzer tends to vary as the square of the cosine of the angle between the polarizer's plane and the analyzer's transmission axis. In the image at left above, the polaroids are crossed, resulting in minimum transmission. By examining the equation, it can be determined that when the two polarizers are crossed ( 90 degrees), the intensity is zero.However, the angle must be in radians instead of degrees, and should be converted by multiplying it by pi/180. The intensity of light transmitted by the analyzer : In summary, when calculating the intensity of transmitted light passing through a polarizer at an angle of 30.0 degrees, the correct equation to use is I1I0cos2 (theta).
