For a finite rod lying along the principal axis of a spherical mirror, which statements are correct?

Select all that apply

• Option A

  Images of the two ends should be located separately for an exact finite-length result.

• Option B

  One transverse magnification cannot generally be used for the whole axial rod.

• Option C

  For a sufficiently short rod, longitudinal magnification gives a good approximation.

• Option D

  The two ends necessarily have identical magnification.
