Santa checks himself for soot, using his reflection in a silvered Christmas tree ornament 0.750 m away. The diameter of the ornament is 7.20 cm. Standard reference texts state that he is a "right jolly old elf," so we estimate his height to be 1.6 m. Where and how tall is the image of Santa formed by the ornament? Is it upright or inverted? Optic axis y=1.6m 5 = 75.0 cm NOT TO SCALE f=R/2 -1.80 cm R=-3.60 cm ဘ S
