Consider the following properties of virtual images:
(A) cannot be projected on the screen
(B) are formed by both concave and convex lens
(C) are always erect
(D) are always inverted
The correct properties are:
(a) (A) and (D)
(b) (A) and (B)
(c) (A), (B) and (C)
(d) (A), (B) and (D)
Answer
Let’s look at each options one by one
-
Real images
are
produced on
a
screen
,
virtual images
are formed
behind the screen.
So, Option (A) is correct
-
For a
convex lens
, virtual image is formed when object is
between O
ptical center
and F
ocus.
A concave lens always forms virtual images.
So, Option (B) is correct
-
Virtual images
are
always erect
.
So, Option (C) is correct
-
But, virtual images are
not inverted
.
But option (D) is incorrect
Thus, (A), (B) and (C) are correct
So, the correct answer is (c)
