An object is placed 10m from a pinhole camera of length 25cm. Calculate the linear magnification.
-
A.
2.5×102 -
B.
2.5×10-2 -
C.
2.5×10-1 -
D.
2.5×101
Correct Answer: Option B
Explanation
(text{Linear Magnification} = frac{text{Length of Camera}}{text{Distance of the Object}})
(text{Linear Magnification} = frac{25}{1000})
(text{Linear Magnification} = 2.5 times 10^{-2})
