- Is the image supposed to be real, virtual, inverted, upright?A tall tree is growing across a river from you. You would like to know the distance between yourself and the tree,as well as its height, but are unable to make the measurements directly. However, by using a mirror to form an image of the tree and then measuring the image distance and the image height, you can calculate the distance to the tree as well as its height. Suppose that this mirror produces an image of the sun, and the image is located 0.8646 m from the mirror. The same mirror is then used to produce an image of the tree. The image of the tree is 0.9468 m from the mirror. (a) How far away is the tree? (b) The image height of the tree has a magnitude of 0.15 m. How tall is the tree?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
- Consider a 2.5-cm tall candle positioned 7.5 cm in front of a concave spherical mirror with a radius of 30 cm. Determine and explain the characteristics of the resulting image. Please create a scaled ray diagram to aid in your explanation. Also, calculate the longitudinal magnification of the candle's image.Famous jeweler Gabi Tolkowsky is looking at a 3.0-cm-tall perfect oval-shaped diamond through a thin lens. The diamond is 20.0 cm behind the lens, and the distance between its upright image and the lens is 40.0 cm. What is the focal length of the lens? Is it converging or diverging? How tall is the image? PLEASE PLEASE draw a ray diagram and define variablesAn object is placed 12 cm in front of a convex mirror of radius 40 cm. Find the position and magnification of the image. State whether the image is real or virtual, and draw a light ray diagram to show the image.
- Q: You hold up a piece of paper by a lens and see the image of a candle projected on the paper. Is this image real or virtual? Q: Will the projected image show the candle right-side-up or upside-down? Q: You look through a concave (diverging) lens at a candle. Will the image you see be smaller or larger in size than the actual candle?A 3.0 cm tall object is positioned 15.5 cm from a converging lens. The focal length of the lens is 10.5 cm. What is the distance to the image? What is the magnification of the image? What is the height of the image? Is the image real or virtual? Is the image inverted or upright?The real image of a concave mirror is six times as large as the object. Determine the image distance (in cm) for an object that is 18.0 cm from the mirror.
