An object when placed in front of a concave mirror between the mirror and its focus, a virtual, magnified and erect image is formed behind the mirror.

#"TS"# is the object. The ray diagram is shown in the figure. The rays of light from #"T"# appear to meet at #"T"'# when extended. Thus #"T"'"S"'# is its image formed.
