Match the corresponding entries of column 1 with column 2.[Where m is the magnification produced by the mirror]
A→pands; B→q and r; C→q and s; D→q and r
A→r and s; B→q and s; C→q and r; D→p and s
A→q and r; B→q and r; C→q and s; D→p and s
A→ pand r; B→ pand s; C→ pand q; D→r and s
Magnification in the mirror, m=-vu
As v and u have same signs so the mirror is concave and image formed is real.
B) m=-12⇒v=u2⇒ Concave mirror and real image.
As v and u have different signs but magnification is 2 so the mirror is concave and image formed is virtual.
As v and u have different signs with magnification 12 so the mirror is convex and image formed is virtual.
