Concept explainers
Two thin convex lenses and an object are arranged as shown below. Two rays from the tip of the object are drawn in order to determine the location of the image produced by lens 1. Lens 2 is placed so that one of its focal points coincides with the location of the image produced by lens 1
- Treating the image produced by lens 1 as an object for lens 2, draw two rays from the tip of this image that pass through lens 2. (Note that one of the principal rays cannot be drawn in this case.)
Using either geometry or trigonometry, show that these two principal rays are parallel on the right side of lens 2. (Hint: Look for congruent fight triangles in your ray diagram.)

- An object is placed to the left of two converging lenses, as shown in (Figure 1). Lens 1 has a focal length f and lens 2 has a focal length 2f. The lenses are separated by a distance of 6 f. An object of height h is then placed a distance of 2f to the left of lens 1. Calculate the following quantities in terms of f and h (specify the Figure "↑ 1 of 1 Part A Start solving the problem by constructing a sketch of the lens system and indicating the focal points of each lens. Write down the thin-lens equation. Express your answer in terms of the focal length f, the object so, and image si distances, if needed. ► View Available Hint(s) VE ΑΣΦ 16f 3 Submit Previous Answers ?

Draw a ray diagram using 3 rays from object # 2 – the object for lens 2 – to identify the final image produced by the two-lens system. Make your diagram neat and clearly labeled. [Given the size of the two lens system, I recommend making the drawing on a separate page with the page turned sideways in landscape orientation.]arrow_forwardYou are imaging a pencil through a thin, converging lens as shown in the image below. If p (the distance from the object to the center of the thin lens) is 8.15m and the focal length of the thin lens is 0.42m, how far away (in meters) from the center of the thin lens is the real image located (the real image will be on the right-side of the lens in this particular example illustrated below)?arrow_forward

The dots represent the focal points of the lens. -0.10 +0.10 At what distance from the lens could the object be placed to produce a virtual image that is smaller than the object (where M < 1)? There is no place where this is possible at -0.10 m only at either -0.25 m or +0.25 m at either -0.05 m or +0.05 marrow_forwardCase 5: Object located in focus (d0= F'). The figure below shows an arrow-shaped object, placed in front of a convex lens at a distance d0 equal to a focal length (d0=F'). Draw the following rays in the figure: ray parallel to the optical axis, central ray. Don't forget to put the direction on each ray, both the incident rays and the transmitted rays. Label each ray with its name. Image characteristics for Case 5: Object located in focus (d0= F').

Then, describe whether the image formed is on the same or opposite side of the object, upright or inverted image, and smaller or bigger than the object. 4) A 19-cm high object is placed 71 cm from a converging lens. The focal length is 35 cm. 5) A 26.50-cm high object is placed 40 cm from a diverging lens. The focal length is 20 cm.arrow_forward

Part A: How far from the second lens is the final image of an object infinitely far from the first lens?arrow_forwardLens L, in the figure below has a focal length of 14.0 cm and is located a fixed distance in front of the film plane of a camera. Lens L, has a focal length of 13.5 cm, and its distance d from the film plane can be varied from 5.00 cm to 10.0 cm. Determine the range of distances for which objects can be focused on the film.

An object is placed 23.0 cm in front of the lens. 1)Where is the final image due to the lens–mirror combination? Enter the image distance with respect to the mirror. Follow the sign convention.

The surface forms an image I and object O? The center of curvature is point c For the ray that passes through the surface along a radial line, its angles of incidence and refraction are both zero, so its direction does not change at the surface. For the ray AB the direction changes according to Snell's law. Question Show that for small angle θ1 and θ2, the Snell's law can be written as n1 tan θ1 = n2 tan θ2arrow_forwardA small silver Christmas ball with a diameter of 6.25 cm was hanging on a Christmas tree.
