Part 1

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 844 W/m2 shines from the sky onto the spider, and that the intensity transmitted by one of the polarizing eyes is 169 W/m2. For this eye, what is the angle between the polarization direction of the eye and the polarization direction of the incident light?

Part 2

What is the intensity transmitted by the other polarizing eye?

    Using our eyes we cannot detect UV and infrared (IR). Ultraviolet detectors generally use either a solid-state device, such as one based on silicon carbide or aluminum nitride, or a gas-filled tube as the sensing element.

    Compound eyes can detect fast movement and sometimes polarization of light. One disadvantage is that each individual lens is very small, and they each diffract light, limiting the possible resolution (images are not very sharp).

    Some argue that the perception of depth also constitutes a sense, but others argue that this is really cognition (that is, post-sensory) function derived from having stereoscopic vision (two eyes) and is not a sensory perception as such.
