A patient cant see objects closer than 40.0 cm and wishes to clearly see objects that are 20.0 cm from his eye. (a) Is the patient nearsighted or farsighted? (b) If the eye-lens distance is 2.00 cm, what is the minimum object distance p from the lens? (c) What image position with respect to the lens will allow the patient to see the object? (d) Is the image real or virtual? Is the image distance q positive or negative? (e) Calculate the required focal length. (f) Find the power of the lens in diopters. (g) If a contact lens is to be prescribed instead, find p, q, and f and the power of the lens.

. (a) In a camera equipped with a 50-mm focal-length lens, the maximum distance that the lens can be from the film is 60 mm. What is the smallest distance an object can be from the camera if its image on the film is to be in focus? What is the magnification? (b) An extension tube is added between the lens and the camera body so that the lens can be positioned 100 mm from film. How close can the object be now? What is the magnification?
A certain slide projector has a 100 mm-focal length lens. (a) How far away is the screen if a slide is placed 103 mm from the lens and produces a sharp image? (b) If the slide is 24.0 by 36.0 mm, what are the dimensions of the image? Explicitly show how you follow the steps in the Problem-solving strategy: Lenses.
1. You have a thin lens of focal length 50 mm. a. The object is 100 mm to the left of the lens. Where is the image located (that is, what is the image distance q, including sign - express in millimeters)? Is the image real or virtual? What is the magnification? b. The object is 1 meter to the left of the lens. Where is the image located (that is, what is the image distance q, including sign - express in millimeters)? Is the image real or virtual? What is the magnification? c. The object is 20 mm to the left of the lens. Where is the image located (that is, what is the image distance q, including sign - express in millimeters)? Is the image real or virtual? What is the magnification?
Part B (work to be submitted): 1. Sunlight is observed to focus at a point 18.5 cm behind a lens. a. What kind of lens is it? b. What is the focal length of the lens? 2. A sharp image is located 3 cm behind a converging lens with a 2 cm focal length. Find the distance from the object to the lens using the thin lens equation. 3. Using the definition of lateral magnification and geometrical considerations prove Equation 3 in this week's laboratory handout (page 4).
Solve and show the solutions by I. Analytical Method - using Lens/Mirror Equation and II. by Graphical Method - Ray Tracing (Indicate your own scale). An object O with a height of 2 cm is placed at a distance of u = 3 cm from the vertex of a lens and has an image distance v = -9 cm. By I. Analytical Method and II. Graphical Method (Use your own scale.) 1. What is the height hi of image I? 2. Determine the magnification. (Round off your final answer up to 2 decimal places.) 3. Describe the image I according to its: a.) size b.) position c.) nature
1 a) Draw a picture that shows the sun's rays passing through a convex glass lens. b.) Label your diagram with the object to lens distance s, the image to lens distance s', and the focal length fof the lens. Why can't you burn a leaf using sunlight with a diverging lens, or with no lens at all?
1. An object is 6.0-cm tall, and it is placed 30.0 cm from a lens with convex focal length 10.0 cm. Create an appropriate scale such that the situation is large on a piece of graph paper. Clearly state the scale you are using. Carefully locate the image distance and the image size with a ray diagram. b) Solve the above problem with mathematics. c) Find the percent difference between the image distance and the image size found above.
Assessment: Solve the following problems in a sheet of paper. 1. Determine the image distance and image height for a 5.5-cm tall object placed 54.0-cm from a converging lens having a focal length of 20.0 cm. 2. Determine the image distance and image height for a 5.0-cm tall object placed 48.0-cm from a converging lens having a focal length of 24.0 cm. 3. Determine the image distance and image height for a 4.8-cm tall object placed 26.0-cm from a converging lens having a focal length of 16.0 cm
Please its urgent…. I'll give you thumbs up. Use 3 principal rays and the lens/mirror equation to find and describe the image for each of the following. Describe means: real/virtual; erect/inverted; bigger/smaller, magnification; where? position from lens/mirror. An object is placed 30 cm in front of a f = +15 cm lens. A mirror f = -20 cm is placed 20 cm from the lens.
We use a lens of focal length f = 4.8 mm in order to project an image of an object AB (height = 1.6 cm) placed at 24 mm of the lens. Determine the position and the size of the image A'B'. 1) Calculation а. Write the thin lens formula b. Use it to determine the distance between the lens and the image. Use this result in order to determine the magnification of the projection. с. d. Determine the size of the image A'B'.
