A point object moves purely transverse to the principal axis while its axial distance from a stationary spherical mirror remains fixed. Which statements are correct?

Select all that apply

• Option A

  The image has no axial velocity in the paraxial approximation.

• Option B

  The transverse magnification remains constant.

• Option C

  The image transverse velocity equals m times the object transverse velocity.

• Option D

  Object and image transverse velocities always have the same direction.
