no i do not know where is that place but i guess it has a INTOLERABLE distance

its obviously so question is how ? You think this formula can help ? f = m ( q - p ) / (m+1)^2 ?

hmmm a good question , i think finding the thickness of the lens its umpossible or its hard and if we want to solve it we must know high level formula ( more than high school ) so probebly it means diagnal

yeh we can realize that the object is near 2F so can it help us to soving the problem ? cos objent can not be in a very far distance

Homework Statement How we can determine The diameter of the lens of the camera approximitly that this picture took with that? ( we know that lens of the camera made by some parts but we count them as a thin one in Practical calculations ) Homework Equations m = q / p 1/f = 1/q + 1/p f =...
