Homework Statement
True or False: If a pinhole camera casts on the screen an image of 40.0cm in size of an object situated at a distance of 40.0m from the camera, then the size of the object is 10.0m.
Homework Equations
M = hi/ho = di/do
The Attempt at a Solution
hi = 40.0cm
do = 40.0m
ho = 10.0m (?)
M = hi/ho = 0.04m
di = dohi/ho = 0.16m
M = di/do = 0.004m
I'm guessing it is FALSE because the two values for M are different but I really have no idea how to go about a question like this. Any help would be greatly appreciated! :D
