PRACTICE IT Use the worked example above to help you solve this problem. A diverging lens of focal length f = -9.9 cm forms images of an object situated at various distances. (a) If the object is placed p₁ = 29.7 cm from the lens, locate the image, state whether it's real or virtual, and find its magnification. 9 = -7.42 cm M = 0.25 (b) Repeat the problem when the object is at p₂ = 9.9 cm. 9 = -4.95 cm 0.17 M X Your response differs from the correct answer by more than 10%. Double check your calculations. (c) Repeat the problem again when the object is 4.95 cm from the lens. a -3.3 cm -0.11 X M Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. EXERCISE HINTS: GETTING STARTED I I'M STUCK! Use the values from PRACTICE IT to help you work this exercise. Repeat the calculation, finding the position of the image and the magnification if the object is 20.6 cm from the lens. q = -6.69 cm 0.23 X M = What factors affect the magnification of an image?
