Transcribed Image Text:1. The diagram below shows a cross-section of a lens and some incident light rays. It also
shows a line called the principal axis (dotted) on which is a point marked "F", which is the
focus of the back side of the lens. Draw the continuation of the light rays as they enter the
lens and converge on the focus.

There is some distortion associated with gathering light rays through a lens; the most
important effect is inversion, which results in an upside-down and backwards image. In
the diagram below, an object (a nail) is shown on one side of a lens and its image is shown
on the other side. The image is called real, because the light rays actually pass through it. A
virtual image is one in which the viewer infers the position of the image by back-tracing
the rays; in other words, the actual light rays do not go through the image.
