Question:
In reading about why an object seems to get smaller with distance I think I read a formula or explanation that went something like this: The apparent size of an object decreases with the square of half the distance. I know this is not accurate. Could you give me the formula that I have mentioned?


Replies:
I think you just said:

Sa=S/(0.5 D)^2

a little bit of rough sketching in front of me seems to indicate that Sa=S/D may be a bit more accurate.
