Concept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem. The distance between an object and its image formed by a diverging lens is 7.40 cm. The focal length of the lens is -4.50 cm. Find (a) the image distance and (b) the object distance.

mpt in Progress Concept Simulation 26.3 reviews the concepts that play a role in this problem. A converging lens has a focal length of 74.00 cm. A 10.0- cm-tall object is located 170.0 cm in front of this lens. (a) What is the image distance? (b) Is the image real or virtual? (c) What is the image height? Be sure to include the proper algebraic sign. (a) Number i Units V (b) The image is (c) Number i Units Hint real virtual

Anne's retina is 1.8 cm from the lens. The nearest object she can see clearly without corrective lenses is 2.0 m away. 1. Sketch a ray diagram to show (qualitatively) what happens when she tries to look at something closer than 2.0 m without corrective lenses. 2. What should the focal length of her contact lenses be so that she can see clearly objects as close as 20.0 cm from her eye?

A certain slide projector has a 118-mm-focal-length lens. Hints Follow the problem-solving strategy steps outlined in "Problem-Solving Strategy: Lenses" in Section 2.4 Thin Lenses. Two additional hints: (1) you are given the focal length and object distance-distance to slide-here; what equation relates these to the image distance? (2) Remember the linear magnification formula. a. To project the image of a slide onto a screen, does this lens need to form a real image or a virtual image? not enough information given virtual image real image b. If a slide is placed 123 mm from the lens, how far from the lens should the screen be placed for a sharp image? mm away from lens. c. If the size of the slide is 36.0 (width) by 24.0 (height) mm, what are the dimensions of the image? Width = mm; Height = mm The film should be positioned at the location of the image to record the image.

a ray diagram for eyeglasses that contain a converging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm

An object is 20 cm to the left of a thin diverging lens that has a 35 cm focal length. What is the image distance i? Number i Units

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 variables

A-6.10-D lens is held 14.5 cm from an ant 1.00 mm high. Part A What is the position of the image? on the opposite side of the lens relative to the object on the same side of the lens with the object no image is formed Previous Answers ✓ Correct Part B Find the image distance.
