Question

Which describes how to generate a real image of an object using a concave mirror?The object must be closer to the mirror than the focal point.
The object must be placed behind the mirror.
The object must be farther from the mirror than the focal point.

Answer 1

In order to form a real image using a concave mirror, the object must be placed beyond the center of curvature of the mirror. Therefore, the object must be further from the mirror than the focal point. The image that will form will be real, but it will also be inverted and its magnification will be less than 1, meaning it will be smaller than the actual object.
