A biologist wishes to examine a tiny aquatic organism using a thin diverging lens of focal length −10cm. The organism is mounted on a slide and placed 15cm in front of the lens along the principal axis.
(1) Part 1: Calculate the numerical value of the image distance si for the organism, including the correct sign convention.
(2) Part 2: Determine the linear magnification M produced by the lens.
(3) Part 3: State whether the image is upright or inverted and whether it is enlarged, reduced, or the same size as the organism. Justify each conclusion using the values obtained in parts (a) and (b).
