A student positions a small arrow-shaped object between a convex (converging) lens and its focal point on an optics bench.
You will analyze the image produced by the lens using qualitative reasoning only—no numerical calculations are required.
(a) On your own paper, draw a principal-axis ray diagram that includes at least three principal rays originating from the tip of the object. Clearly indicate the lens, its focal points on both sides, the principal axis, and the approximate location of the image formed.
(b) Using the construction from part (a), describe the following characteristics of the image and justify each characteristic based on features of the ray diagram.
• Whether the image is real or virtual
• Whether the image is upright or inverted
• Whether the image is enlarged, reduced, or the same size as the object
