An unpolarized beam of light is incident on a stack of ideal polarizing filters. The axis of the first filter is perpendicular to the axis of the last filter in the stack. Find the fraction by which the transmitted beams intensity is reduced in the three following cases. (a) Three filters are in the stack, each with its transmission axis at 45.0 relative to the preceding filter. (b) Four filters are in the stack, each with its transmission axis at 30.0 relative to the preceding filter. (c) Seven filters are in the stack, each with its transmission axis at 15.0 relative to the preceding filter. (d) Comment on comparing the answers to parts (a), (b), and (c).
In Figure P37.52, suppose the transmission axes of the left and right polarizing disks are perpendicular to each other. Also, let the center disk be rotated on the common axis with an angular speed . Show that if unpolarized light is incident on the left disk with an intensity Imax, the intensity of the beam emerging from the right disk is I=116Imax(1cos4t) This result means that the intensity of the emerging beam is modulated at a rate four times the rate of rotation of the center disk. Suggestion: Use the trigonometric identities cos2=12(1+cos2) and sin2=12(1cos2). Figure P37.52

If a light beam of intensity I0 that is unpolarized is incident on P1, what is the intensity of the transmitted light after the first two polarizers?
A beam of unpolarized light of intensity 4.04E3 W/m2 passes through a series of ideal polarizing filters with their polarizing directions turned to various angles as shown in the figure. If the middle polarizer is removed, what is the light intensity at point C (in W/m2)?
One way to produce a beam of polarized light with intensity I and polarization angle θ would be to pass unpolarized light with intensity I0 through a polarizer whose transmission axis is oriented such that θTA=θ. How large must I0 be if the transmitted light is to have intensity I? Express your answer as a decimal number times the symbol I. For example, if I0=(1/4)I, enter 0.25 * I.
A beam of polarized light with intensity I0 and polarization angle θ0 strikes a polarizer with transmission axis θTA. What angle θ should be used in Malus's law to calculate the transmitted intensity I1? This process is illustrated in the figure (Figure 2), where the polarization of the light wave is visually illustrated by a magenta double arrow oriented in the direction of polarization, the transmission axis of the polarizer is represented by a blue double arrow, and the direction of motion of the wave is illustrated by a purple arrow. θ0 θTA θTA−θ0 θTA+θ0 (θTA−θ0)/2 What is the polarization angle θ1 of the light emerging from the polarizer? θ0 θTA θTA−θ0 θTA+θ0 (θTA−θ0)/2
Three polarizing disks whose planes are parallel and centred on common axis. The directions of their transmission axes relative to the vertical are respectively: θ1 = 38o clockwise, θ2 = 25o counter-clockwise, and θ3 = 12o clockwise.

Consider a set of three polarizers. Polarizer 1 has a vertical transmission axis, and polarizer3 has a horizontal transmission axis. Taken together, polarizers 1 and 3 are a pair of crossedpolarizers, so that when a beam of unpolarized light shines on polarizer 1 from the left, nolight emerges from polarizer 3. Polarizer 2, with a transmission angle at 45° to the vertical,is now placed between polarizers 1 and 3, as shown in the sketch. (a) Is the transmission oflight through the three polarizers zero or nonzero? (b) Which of the following is the bestexplanation for your prediction?I. No light can pass through the crossed polarizers 1 and 3, regardless of what other polarizers are placed between them.II. Polarizer 2 changes the polarization direction by 45°, and light can now pass throughpolarizer 3
