AP Physics 2
13.4 Images Formed by Lenses
A student conducts two separate optical trials on an optical bench using two different thin spherical lenses, Lens 1 and Lens 2. In each trial, an object is placed at an object distance of d_o = 30 cm to the left of the lens. The student records the data in the table shown.
Which of the following correctly identifies the focal length f_1 of Lens 1, the image distance d_i for Lens 2, and the focal length f_2 of Lens 2?
| Trial | Lens | Object Distance (d_o) | Image Distance (d_i) | Magnification (M) | Image Orientation |
|---|---|---|---|---|---|
| 1 | Lens 1 | +30 cm | +60 cm | -2.0 | Inverted |
| 2 | Lens 2 | +30 cm | ? | +0.50 | Upright |
Which of the following correctly identifies the focal length f_1 of Lens 1, the image distance d_i for Lens 2, and the focal length f_2 of Lens 2?
