Convex Mirror & Virtual images

  1. Mar 27, 2013 #1
    1. A spherical mirror is used to form an image 5 times as tall as an object, on a screen positioned 5.0m from the mirror.
    a) Describe the type of mirror required
    b) Where should the mirror be positioned relative to the object




    2. M = (Di)/(Do) & 1/(Di) + 1/(Do) = 1/(F)



    3. I have solved the problem ( assuming Di = -5) getting Do = 1. m & the mirror being a convex mirror. However how it possible for a virtual image to be projected onto a screen? Thanks

    A virtual image cannot be projected onto a screen. Is there a way to get a real image 5 times taller than the object? (The problem does not say that the image must be upright. The image might be inverted.)

    It is not virtual. What type of shpherical mirror produces a real image? Between what two positions on the axis should the object be to get an enlarged real image?
