The corneaâs refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The iris works like a shutter in a camera. It has the ability to enlarge and shrink, depending on how much light is entering the eye.ight rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape. In a normal eye, the light rays come to a sharp focusing point on the retina. The retina functions much like the film in a camera.

All the information you need to determine how many pies to order can be found in the pizza itself. Because what is a pizza if not a tool for learning fractions? Typically, pizzas are cut into eight slices, making each slice one-eighth of a pizza. If a hungry person can eat three slices of pizza, and each pizza has eight slices, how many pies should you order for your group? The answer is. X * â = P. where X is the number of guests, and P is the number of pies you should order. If you are seeing this after you ordered, you can also move the variables around and solve for X to figure out how many people are going to go hungry because you used your brain instead of the Pizza Equation.
