Prelab Name Class Section The image of an object through a lens can be found as the intersection of two light rays starting from the tip of the object. Any two rays can do. Two convenient ones are: 1) the ray passing through the center of the lens, as it does not get deflected; 2) the ray perpendicular to the axis of the lens, as it gets deflected through the focus of the lens. The attached drawing shows an object...

1. Shown is a device that displays a real image. Two identical
spherical mirrors are put together as shown in figure. The
reflective surfaces of the mirrors face each, and the top mirror
has a small hole at its vertex that allows light to enter the
volume between the mirrors. When an object (shown as an arrow) is
placed at the bottom of the lower mirror, a real image of the
object appears right at the opening of the top...
