Science Question on Spherical Mirrors
No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be
A
only plane.
B
only concave
C
only convex.
D
either plane or convex.
Answer
either plane or convex.
Explanation
Solution
A convex mirror always gives a virtual and erect image of smaller size of the object placed in front of it. Similarly, a plane mirror will always give a virtual and erect image of same size as that of the object placed in front of it. Therefore, the given mirror could be either plane or convex.
So, the correct option is (D): either plane or convex.
