A curious child is looking at ants with a magnifying glass. If she holds the convective lens 5 cm from an ant 3 mm long, determine the magnification of the image the girl sees. Is the image upright? Take f = 10 cm and show ray tracing diagram to prove your answer.

When a person holds a magnifying glass 8.0 cm away from an object that is 2.0 cm wide, she sees a virtual image of the object, which is 6.0 cm wide. What is the focal length of the magnifying glass? Provide a drawing using the ray tracing rules.
You hold a magnifying glass up to a flower. The magnifying glass has a focal length of 6.0 cm and you hold the flower 4.0 cm from the glass. What is the distance from the glass that you see the image? What is the magnification? Use a scaled ray tracing diagram! Focal point Virtual image Object
Number 9 The end of the spring semester means graduation and receptions. I pick up the empty punch bowl, which is shiny silver on both sides and appears to be a section of a sphere. When I look into the punch bowl I see an image of my face that appears to be 24.0 cm behind the bowl. I flip the bowl over and look at its bottom and now see an image of my face that is 8.00 cm...
please I need answers to all questions because am writing text on Friday. 7. Suppose an object such as a book page is held 7.50 cm from a concave lens of focal length -1C em. Such a lens could be used in eyeglasses to correct pronounced nearsightedness. (a) Using the thin le equations to calculate the location of the image. (b) What magnification is produced? (c) Use ray tracing get an approximate location for the image. 8. The left face...
Parts a through d are a part of the SAME problem. THANK YOU in advance! 3. Single converging (convex) lens: Suppose an object is placed a distance 8 cm to the left of a convex lens of focal length 10 cm. (a) On a separate sheet of paper, make a scaled ray drawing. Use a ruler. A free hand sketch is not acceptable State whether the image is real or virtual and upright or inverted the lateral magnification of the...
A biconcave lens is made with glass (n 1.36) and has a magnitude of curvature T1 - 1.0 cm on the front surface and a magnitude of curvature T2-7.0 cm on the back surface, as pictured. r1 r2 This lens is in air and you may use the lensmaker's equation n- 1 to find other relationships in this problem, if needed. We place an object of height h 4.08 mm a distance s-6.0 cm from the center of the lens...
