Answer 2

Answer;

D. An image that is smaller than the object and is behind the mirror

Explanation;

• Magnification is the ratio of the height of the image to the height of the object.
• When magnification, m, is greater than 1 the image is larger than the object, and when m is less than 1 means the image is smaller than the object.
• If the magnification is positive, the image is upright compared to the object; if m is negative, the image is inverted compared to the object.
• Magnification is negative when the image is inverted, therefore a real image.
