Question

what is the difference in magnification in these two tables

c. Determining the Thin Lens Equation: Consider a lens of focal length f= +10 cm. The object distances and its image distances from the lens are showed in two tables below. Object Image Object Image Distance Distance Distance Distance d. (cm) di(cm) d. (cm) di(cm) 13 43.0 22 18.5 14 35.0 25 16.8 15 30 14.8 29.0 35 14.2 16 26.5 40 13.1 17 24.0 45 12.9 18 22.5 50 12.5 19 21.1 55 12.2 20 20.1 Right Table: Object distance > 2f Left Table: Object distance < 2f
