REAL, INVERTED, SAME SIZE, PARALLEL TO C. REAL, INVERTED, ENLARGED, BEFORE C. NO IMAGE IS FORMED IF OBJECT IS AT FOCAL POINT. VIRTUAL, UPRIGHT, ENLARGED. QUESTION ANSWER Concave vs. Plane mirrors always produce virtual images which are upright and located behind the mirror; they are always the same size as the object Plane mirrors Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object. REAL IMAGE Only a concave mirror can be used to produce a real image; and this only occurs if the object is located at a position of more than one focal length from the concave mirror. Plane mirrors never produce real images. VIRTUAL IMAGE A plane mirror will always produce a virtual image. A concave mirror will only UPRIGHT IMAGE INVERTED IMAGE produce a virtual image if the object is located in front of the focal point. A plane mirror will always produce an upright image. A concave mirror will only produce an upright image if the object is located in front of the focal point. Only a concave mirror can be used to produce an inverted image; and this only occurs if the object is located at a position of more than one focal length from the concave mirror. Plane mirrors never produce inverted images. Are all real images No. Real images can be larger than the object, smaller than the object, or the larger than the object? same size as the object.
