A car driver uses a rear-view mirror to observe vehicles behind. If the mirror were replaced with a concave mirror of the same size, which of the following is the most likely consequence for the image of a car far behind?
The image would appear inverted and could be larger or smaller depending on the position
A rear-view mirror is a convex mirror, which always makes an erect, diminished image and gives a wide field of view.
A concave mirror, by contrast, forms a real and inverted image when the object is beyond its focal length; the image size depends on where the object is.
So using a concave mirror in place of the rear-view mirror would show vehicles behind as inverted, and larger or smaller depending on their distance.
Hence, the answer is The image would appear inverted and could be larger or smaller depending on the distance of the object.
