To find the focal length of a concave mirror.


            Formula = 1/u + 1/v = 1/f

            Errors = opinion when image is sharpest. Ruler accurate to +/-1mm.

            Accuracy = Do experiment many times.

An approximation of the focal length was found so as to ensure object was placed outside it and therefore ensuring a real image is being produced.
