    I am having problems with convex and concave mirrors. here is the problem

    Consider a convex minor, with a focal length of -81.2mm. An object is placed 80mm away from the mirror. what is the image position?


    i have that software Pearls which seems to help me. But it doesn't say how thick the mirror is suppose to be for that problem so I am pretty much lost.
    any help I would greatly appreciate it.
