Question: An object is 1.0 cm tall and its inverted image is 4.0 cm tall. What is the exact magnification? I figured I would post this to help others out. The correct answer is -4.0 . since the image is inverted, the magnification is negative. M= hi/ho. The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
