17. An object, pointing upwards, is placed outside the focal point F1 of a thin converging lens. A student is using the diagram shown below and the graphical method to predict the image of the arrow. She draws several rays from point Q to the lens. Which principal ray will pass through the lens undeflected?

The diagram shows 2 out of the 3 possible principal rays traversing a thin lens of unknown type. The focal points are labeled F1 and F2, the object is at 0, and the image is at I. Which of the following statements are true? Select one or more: O a. This is a divergent lens. Ob. This is a convergent lens. Oc. The magnification is about-2 Od. The magnification is about 2. De. The image is virtual. Of The image is real

An object is placed 45.0cm to the left of lens A. Lens B is placed 40.0cm to the right of lens A. Lens A is converging and has a focal length of 20.0cm . Lens B is converging and has a focal length of 10.0cm . a. What is the final image position relative to lens B? (Include the + or – sign.) b. What is the overall magnification? (Include the + or – sign.) c. Is the final image real or virtual? d. Is the final image upright or inverted?

A 1.0-cmcm-tall object is 9.0 cmcm in front of a converging lens that has a 40 cmcm focal length. Calculate the image position. Express your answer with the appropriate units. Enter positive value if the image is on the other side from the lens and negative value if the image is on the same side as the object. Calculate the image height. Express your answer with the appropriate units

Create a ray diagram for eyeglasses that contain a diverging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm. What type of vision are they used to correct? Give both names. How do they do this? Explain.

A person looks at a gem using a converging lens with a focal length of 13.8 cm. The lens forms a virtual image 33.1 cm from the lens. Find the magnification. Describe the image. 1. real, upright, larger 2. real, inverted, larger 3. virtual, upright, larger 4. real, inverted, smaller 5. virtual, inverted, larger 6. real, upright, smaller 7. virtual, inverted, smaller 8. virtual, upright, smaller

Thin lenses. Object O stands on the central axis of a thin symmetric lens. For this situation, each problem in the table (below) gives object distance p (centimeters), the type of lens (C stands for converging and D for diverging), and then the distance (centimeters, without proper sign) between a focal point and the lens. Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real or virtual, (d) inverted from object O or noninverted, and (e) on the same side of the lens as object O or on the opposite side.
