Answer 1

Answer:

the magnification is one half, then the image appears to be half the size of the object. The sign of the magnification tells us the orientation of the image. If the sign is positive, then the image is upright. If the sign is negative, then the image is upside-down.

A 5-cm-high object is placed in front of a concave mirror with a radius of curvature of 20 cm. Determine the image height if the object distance is 5 cm, 15 cm, 20 cm, 30 cm. The minus sign indicates that the image is virtual or the image is behind the mirror. The plus sign indicates that the image is upright.
