Question

An optical component and an object S placed along its optic axis are given in Column I. The distance between the object and the component can be varied. The properties of images are given in Column II. Match all the properties of images from Column II with the appropriate components given in Column I:

Column I		Column II
A		P	Real image
B		Q	Virtual image
C		R	Magnified image
D		S	Image at infinity

• A. $( A ) \rightarrow( P ),( Q ),( R ),( S ) ;( B ) \rightarrow( Q ) ;( C ) \rightarrow( Q ),( R ),( S )$ $( D ) \rightarrow( P ),( Q ),( S )$
• B. $( A ) \rightarrow( P ),( R ),( S ) ;( B ) \rightarrow( Q ) ;( C ) \rightarrow( P ),( Q ),( R ),( S ) ;$ $( D ) \rightarrow( P ),( Q ),( R ),( S )$
• C. $( A ) \rightarrow( P ),( Q ),( R ),( S ) ;( B ) \rightarrow( Q ) ;( C ) \rightarrow( P ),( Q ),( R )$, $(S) ;(D) \rightarrow(P),(Q),(R),(S)$
• D. $( A ) \rightarrow( Q ),( R ),( S ) ;( B ) \rightarrow( Q ) ;( C ) \rightarrow( P ),( Q ),( S )$ $(D) \rightarrow(P),(Q),(R),(S)$

Answer 1

Answer: (C)

$( A ) \rightarrow( P ),( Q ),( R ),( S )$
For a concave mirror when the object lies beyond $F$ till $\infty$, a real image is
formed. When it lies within focal length a virtual image is formed. When it
lies within radius of curvature image is magnified. When it lies at the
focus, image is formed at $\infty$
Simply, a concave mirror can produce all type of images.
$( B ) \rightarrow( Q )$
For a convex mirror, for any position of the object, the image is always
virtual, erect and smaller in size than the object.
$( C ) \rightarrow( P ),( Q ),( R ),( S )$
Same explanation, as above, for the convex lens as in option $( A )$.
$( D ) \rightarrow( P ),( Q ),( R ),( S )$
A positive meniscus lens can produce all four types of images.
