A concave spherical mirror has a focal length of 10cm. For a particular experimental setup, the magnitude of magnification is required to be exactly 2.
Solve the following:
(i) Obtain the possible values of the object distance u that give a magnification of magnitude 2. State all working steps clearly.
(ii) For each object distance obtained in part (i), calculate the corresponding image distance v.
(iii) For each case, state whether the image produced is real or virtual and comment on its orientation.
