The ground spider Drassodes cupreus like many spiders, hasseveral pairs of eyes. It has been discovered that one of these pairs of eyes acts as a set of polarizationfilters with one eye's polarization direction oriented at 90° to the other eye's polarization direction. Inaddition, experiments show that the spider uses these eyes to aid in navigating to and from its burrow.Explain how such eyes might aid navigation.

We need to figure out why ground spiders, particularly Drassodes cureus yes, make navigating easier.

Suppose you want to rotate the plane of polarization of a beam of polarized light by 67°, but you do not want the final intensity to be less than 88% of the initial intensity. What is the minimum number of polarizing sheets you must use? Assume that each sheet is rotated the same angle relative to the adjacent sheets.

Physics Polarization: Write down the equations of an unpolarized E field before it hits a linear polarizer that is polarized in the x-direction. What are the E field equations after the linear polarization? I'm having extreme difficulty on this problem, need some guidance.
Many modern sunglasses are advertised as being polarized. Manufacturers make lenses that are polarized vertically, so as to block off horizontally polarized light coming from reflections from the ground and other flat surfaces, thus reducing glare. If you bought a new pair of polarized sunglasses (and perhaps didn’t care about disassembling it into pieces), how could you verify that the lenses are indeed polarized?
Experiments show that the ground spider Drassodes cupreus uses one of its several pairs of eyes as a polarization detector In fact, the two eyes in this pair have polarization directions that are at right angles to one another Suppose linearly polarized light with an intensity of 775 W/m² shines from the sky onto the spider and that the intensity transmitted by one of the polarizing eyes is 774 W/m². For this eye, what is the angle between the polarization direction of the eye and the polarization direction of the incident light?
Three perfect polarizers are placed in sequence and receive incoming light from one side as shown in the figure below. The first polarizer has its optic axis oriented vertically. The second is oriented 0 = 33.8 degrees to one side of vertical. The third is oriented horizontally.

Light passes through two different polarizers. The first is aligned vertically, while the second is aligned horizontally. How much light makes it through the two polarizers?
** 46. How much unpolarized light gets through a polarizer? Unpolarized light is as likely to have its polarization vector in one direction as another. Therefore, on average, the up-down component of the polarization vector for unpolarized light will be the same as the right- left component. These equal components in two perpendicular directions are in the same relationship as the E-field components when polarized light hits a polarizer with its polariza- tion vector at 45° to the optic axis. We can use this connection to find out what fraction of the energy in an incident unpolarized beam makes it through the polarizer as polarized light. a) If an electric field vector of a polarized light beam is 45° to the optic axis of the polar- izer, find the ratio between the magnitude of the electric field vector that passes through the polarizer and the magnitude of an incident polarized electric field vector. This will be the same as the ratio of the magnitude of the electric field of the…
You have three polarizers. If incident light is polarized at 30 degrees to the vertical, aligned with the transmission axis of polarizer B (which also has its transmission axis 30 degrees to the vertical), and polarizer C has transmission axis at 90 degrees to the vertical, in what order should the polarizers be placed for maximum intensity? Is there more than one answer? Would it be A,B,C or B,A,C?
