Question 7 10 pts A converging lens has a focal length of 10 cm. Locate the image of an object at a distance of 15cm from the lens. Which of the ray tracing diagrams depicts the correct location and magnification of the image? Hint: To pick the correct figure, you need to determine if the image is real or virtual, upright or inverted and find the magnification. image object object image Fig. 2 Fig. 1 image object object F image Fig. 4 Fig. 3 image object Fig. 5 fig. 1 O fig. 2 O fig. 3 fig.4 O fig.5Question 8 10 pts What magnification will be produced by a lens of power -4.00 D (such as might be used to correct myopia) if an object is held 24 cm away? Your answer should be a number with two decimal places. Hint: you need to first determine the focal distance of the lens
