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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
\(\text{Linear Magnification} = \frac{\text{Length of Camera}}{\text{Distance of the Object}}\)
\(\text{Linear Magnification} = \frac{25}{1000}\)
\(\text{Linear Magnification} = 2.5 \times 10^{-2}\)
