An object is placed 20cm from a concave mirror of focal length 10cm. The linear magnification of the image produced is?
-
A.
0 -
B.
(frac{1}{2}) -
C.
1 -
D.
2
Correct Answer: Option C
Explanation
(frac{I}{V}) = (frac{1}{f}) – (frac{1}{u})
(frac{I}{V}) = (frac{1}{10}) – (frac{1}{20})
= (frac{1}{20}) V
V = 20cm.
M = (frac{V}{U})
= (frac{20}{20})
= 1
