- People who do very detailed work close up, such as jewelers, often can see objects clearly at much closer distance than the normal 25 cm. (a) What is the power of the eyes of a woman who can see an object clearly at a distance of only 8.00 cm? (b) What is the image size of a 1.00-mm object, such as lettering inside a ring, held at this distance? (c) What would the size of the image be if the object were held at the normal 25.0 cm distance?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_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
- q37 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_forwardAn 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_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
- Please Asaparrow_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_forwardAnswer 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_forward
- 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?arrow_forwardFor this problem, I know the answer is A but I do not know how to get there. Seeing the steps and equations would be much appreciated. Thank youarrow_forwardAn object that is 2.0 cm tall is located 5.0 cm behind the vertex of a converging lens with a focal length of 10 cm as shown in the diagram below. Which of the lettered choices below gives the correct image characteristics? Specifically, what willI be the height, orientation, and nature of the final image? 10 cm Object İ50 5.0 cm f Converging Lens a. 3.0 cm, inverted, real b.4.0 cm, upright, virtual c. 5.0 cm, upright, real d. 4.0 cm, inverted, virtual e. 2.5 cm, upright, virtual O O O O Oarrow_forward
