- A microscope with an overall magnification of 800 has an objective that magnifies by 200. (a) What is the angular magnification of the eyepiece? (b) If there are two other objectives that can be used, having magnifications of 100 and 400, what other total magnifications are possible?arrow_forwardA doctor examines a mole with a 15.0-cm focal length magnifying glass held 13.5 cm from the mole. (a) Where is the image? (b) What is its magnification? (c) How big is the image of a 5.00 mm diameter mole?arrow_forward(a) What magnification is produced by a 0.150 cm-focal length microscope objective that is 0.155 cm from the object being viewed? (b) What is the overall magnification if an 8 x eyepiece (one that produces an angular magnification of 8.00) is used?arrow_forward
- Two thin lenses with focal lengths of magnitude 15.0 cm, the first diverging and the second converging, are placed 12.00 cm apart. An object 3.00 mm tall is placed 5.50 cm to the left of the first (diverging) lens. Where is the image formed by the first lens located? Please provide a detailed explanation of the process. How far from the object is the final image formed? Please describe the steps taken to reach to your conclusion.arrow_forwardq37 An object (height = 8.2 cm) and its image are on opposite sides of a converging lens. The object is located 19.0 cm from the lens. The image is located 5.5 cm from the lens. Determine the magnification. Enter the numerical part of your answer to two significant figures. Hint: Remember that the sign of the magnification is significant.arrow_forwardWe 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'.arrow_forward
- An object is 19.5 cm from the center of a spherical silvered-glass Christmas tree ornament 6.20 cm in diameter. ▼ Part A What is the position of its image (counting from the ornament surface)? Follow the sign rules. Express your answer with the appropriate units. s' = Submit ▾ Part B m = HA Value Submit Request Answer What is the magnification of its image? VG ΑΣΦ Units Request Answer PYREX ? ?arrow_forwardA diverging lens has a focal length of 20.0 cm. Use graph paper to construct accurate ray diagrams for object distances of (a) 40.0 cm and (b) 10.0 cm. In each case determine the location of the image from the diagram and the image magnification, and state whether the image is upright or inverted. (c) Estimate the magnitude of uncertainty in locating the points in the graph. Are your answers and the uncertainty consistent with the algebraic answers found in Problem 33?arrow_forwardImagine you were provided with a lens, lens holder, screen, sheet of paper, meter rule, clamp& stand, cross wires(object) and a touch light source. Identify the type of lens you have been provide with. Explain your answer Hence write down: two characteristics of the image formed the distance d of the image formed from the lens what is the significance of d? Justify your answerarrow_forward
- Answer the following questions about magnification with expressions: a) What magnification is produced by a “f” focal length microscope objective that is “d_o” from the object being viewed? b) What is the overall magnification if an Mx eyepiece (one that produces an angular magnification of M) is used? Give in terms of M and the variables given in part a.arrow_forward1. 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?arrow_forwardYou need to record an image on a flat array of CCDs (charge coupled devices—basically a detector). You have two convex lenses mounted in a tube to which you will also attach the CCD plane. The first lens has a focal length of 15 mm and is positioned 25 mm from the sample to be imaged. The second lens, with a focal length of 10 mm, is closer to the CCDs and is 50mm from the first lens. How far away from the second lens will you mount the CCD plane? You must solve this problem using a good diagram and geometry. It is not permissible to use the lens/mirror equation, except to check your answer.
