An object is placed 10m from a pinhole camera of length 25cm. Calculate the linear magnification.
-
A.
2.5x102
-
B.
2.5x10-2
-
C.
2.5x10-1
-
D.
2.5x101
Correct Answer: Option B
Explanation
\(\text{Linear Magnification} = \frac{\text{Length of Camera}}{\text{Distance of the Object}}\)
\(\text{Linear Magnification} = \frac{25}{1000}\)
\(\text{Linear Magnification} = 2.5 \times 10^{-2}\)
