A beam of light is polarized all along the y-axis, and passes through a polarizer that has its polarization axis 45° from the y-axis.
1) What fraction of the original electric field amplitude E0 makes it through the polarizer? What direction is it now polarized in?
2) Knowing that the intensity of light is proportional to the square of the amplitude of the electric field, what fraction of the original intensity I0 makes it through the polarizer?

A linearly polarized beam of light of intensityI0 is propagating in the +z direction and its direction of polarization makes an angle of 64° with the x-axis (the angle between the initial direction of polarization and the transmission axis of the first polarizer is 26° as described below). Two linear polarizing sheets are lined up perpendicular to the beam. The first sheet has its transmission axis at an angleθ1 = 90° with respect to the x-axis. The transmission axis of...

To understand polarization of light and how to use Malus's law to calculate the intensity of a beam of light after passing through one or more polarizing filters. The two transverse waves shown in the figure(Figure 1) both travel in the +z direction. The waves differ in that the top wave oscillates horizontally and the bottom wave oscillates vertically. The direction of oscillation of a wave is called the polarization of the wave. The upper wave is described as polarized...

A beam of polarized light passes through a polarizing filter. When the angle between the polarizing axis of the filter and the direction of polarization of the light is 29 ∘, the intensity of the emerging beam is I A) If you instead want the intensity to be I/2, what should be the angle between the filter axis and the original direction of polarization of the light?

When a beam of light passes through a pair of polarizing filters (polarizer and analyzer), the intensity of the transmitted light is a maximum when the transmission axes of the polarizer and analyzer are parallel to each other (θ = 0° or θ= 180°) and zero when the axes are perpendicular to each other (θ = 90°). For any value of theta between 0° and 90° the transmitted intensity is given by I = Ii cos2(θ) where Ii is the...
