APFIVE Concave Mirror Magnification and Image Distance
A concave mirror forms an image with magnification $$m = -0.5$$. If the object is moved to a new position such that the magnification becomes $$m = -2.0$$, how does the new image distance ($$d_i'$$) compare to the original image distance ($$d_i$$)?
