    Converging Lens

    An object is 30.0 cm to the left of a converging lens whose focal length is 50.0 cm. 1) Draw a ray diagram to scale and from it determine the image distance and the magnification. 2) Use the thin-lens and magnification equations to verify your answers to part 1.

    Light 22.34

    Work this problem using the thin-lens equation: A diverging lens with focal length of 25 cm is used to view a postage stamp 50 cm from the lens. (a) How far from the lens does the stamp appear? (b) What is the magnification of the image? Work this problem by ray tracing? I need to see each step and formula to solve this ques

    Diverging Lens Focal Length

    A diverging lens with focal length of 25 cm is used to view a postage stamp 50 cm from the lens. (a) How far from the lens does the stamp appear? (b) What is the magnification of the image? Work this problem by ray tracing?

    The Thin-Lens Equation

    An image of a flower is produced on a screen by a lens 1.60 m from the screen. The image of the flower has a linear magnification of -2.5. What is the focal length of the lens?

    The Magnification of a Lens

    An object is in front of a converging lens (f = 0.30 m). The magnification of the lens is m = -4.0. (a) Relative to the lens, in what direction should the object be moved so that the magnification changes to m = -4.0? (b) Through what distance should the object be moved?

    Optics Diopter lens

    Assume that a person needs a -8.0 diopter lens spaced 15mm from the eye to correct for myopia (nearsightedness). If the person were to remove their glasses how far from the retina does the object come to focus?

    What focal length of lens to image the object at a magnification of -3

    Assume that you have an object that you want to image onto a viewing screen 1500mm away from the object. What are the possible image magnifications if you image the object onto the screen with a thin lens of focal length f=160mm? What focal length of the lens would you need to image the object at a magnification of -3?

    Lens magnification derivation

    Using the figure determine the formula for magnification m in terms of z and z'. Also determine the formula in terms of l and l' ... please see attached

    Products Liability

    I am trying to figure out which rule or law, application and conclusion can be drawn here. I have posted a case as an example. I read that it was settled for monetary amount. See below. National Plaintiffs' Management Committee prosecuting Roberts v. Bausch & Lomb, Inc. (Decided by U.S. District Court, Northern District of

    Galilean Telescope Lenses

    Consider a Galilean telescope, as illustrated in Figure 27-23, constructed from two lenses with focal lengths of 70.8 cm and -15.7 mm. Please see attached.

    Lenses/telescope

    Hi. Can someone please show me how to do the following problem? Thank you. "The Moon has an angular size of 0.50° when viewed with unaided vision from Earth. Suppose the Moon is viewed through a telescope with an objective whose focal length is 51 cm and an eyepiece whose focal length is 51 mm. What is the angular size of th

    Lenses/Compound Microscope

    Hi. Can someone please show me how to do the following problem? Thank you. "A compound microscope has the objective and eyepiece mounted in a tube that is 18.0 cm long. The focal length of the eyepiece is 2.28 cm, and the near-point distance of the person using the microscope is 25.0 cm. If the person can view the image produ

    Converging Lenses

    A converging lens has a focal length of 30 cm. An object that is 20 cm tall is placed 45 cm from the lens. 1. What is the image distance? a. 45 cm, other side of lens b. 20 cm, same side of lens c. 100 cm, other side of lens d. 30 cm, same side of lens 2. Is the image upright or up-side-down?

    What is the height (including sign) of her image on the film

    A camera is supplied with two interchangeable lenses, whose focal lengths are 35.0 and 150.0 mm. A woman whose height is 1.80 m stands 7.00 m in front of the camera. What is the height (including sign) of her image on the film, as produced by a 35.0-mm and 150.0-mm lens?

    Macro Lens Distance

    A macroscopic (or macro) lens for a camera is usually a converging lens of normal focal length built into a lens barrel that can be adjusted to provide the additional lens-to-film distance needed when focusing at very close range. Suppose that a macro lens (f = 53.0 mm) has a maximum lens-to-film distance of 271 mm. How close ca

    Find the location of the image and its character

    A convex lens of focal length 7.5 cm is placed 12 cm to the left of a convex lens with a focal length of 6.5 cm. An object is placed 10.0 cm to the left of the lens with a focal length of 7.5 cm. Find the location of the image and its character (e.g., real, inverted) (A ray diagram may prove to be helpful also). Thank you
