Many nocturnal animals demonstrate the phenomenon of eyeshine, in which their eyes glow various colors at
night when illuminated by a flashlight or the headlights of a car (see the photo). Their eyes react this way because
of a thin layer of reflective tissue called the tapetum lucidum that is located directly behind the retina. This tissue
reflects the light back through the retina, which increases the available light that can activate photoreceptors, and
thus improve the animal's vision in low-light conditions. If we assume the tapetum lucidum acts like a concave
spherical mirror with a radius of curvature of 0.750 cm, how far in front of the tapetum lucidum would an image
form of an object located 30.0 cm away? Neglect the effects of the other structures of the eye, such as the cornea
and lens.
