A man 1.5m tall is standing 3m in front of a pinhole camera whose distance between the hole and the screen is 0.1m. What is the height of the image of the man on the screen?
0.05m
0.15m
0.30m
1.00m
解释
\(h_i = \frac{h_o \times V}{u}\)
\(h_i = \frac{1.5 \times 0.1}{3}\)
= 0.05m
\(h_i = \frac{1.5 \times 0.1}{3}\)
= 0.05m
