A spherical mirror is polished on both sides, when convex side is used for reflection the magnification for an object is found to be 
.The magnification when its concave surface is used for reflection (assuming object at same distance) :
A
– 
B
C
–2
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
D
For convex,
u = –x
m = + 
⇒ v = – 4m = 
+ 
= 
– 
+ 
= 
x = f
For concave, if u = –f
v = ∞ , m = ∞
