Answer 1

Answer:For ideal conditions, in optics problems, we take into consideration ideal lens and mirrors. The focal length of a lens or mirror is dependent on the radius of curvature. So even if the mirror is cut in two, the radius of curvature doesn’t change and so focal length stays same.

Explanation:Thus the image distance (and subsequently the magnification) would now depend on where the object is placed, or the object distance

Answer 2

Answer:

The height of the image is 6 cm.
