Optics - What is the magnification of this image

  1. Feb 26, 2005 #1
    A concave spherical mirror can be used to project an image onto a sheet of paper, allowing the magnified image of an illuminated real object to be accurately traced. If you have a concave mirror with a focal length of 8.0 cm, where would you place a sheet of paper so that the image projected onto it is twice as far from the mirror as the object is?

    cm

    What would the magnification of the image be?

    The image is real and inverted.

    Hi,
    This is my first time using this website. I am not sure what exactly I need to include, but I do know the equations for magnification. I do not understand how to find the image they are looking for nor the magnification. Also I was wondering if someone could tell me how to find the radius of curvature.

    Thank you

    To start with use you image/object/focal length relationship, set i = 2o, then solve for o.

    What is your definition of magnification?
