With the use of our lense [the distance of it from our plate (sensor)] we are managing the light rays of our subject of interest to convergence on our plate, that`s when we have in focus objects.

why is the highest focus infinity? Please someone answer.

it could be because if you change something on a real camera. The numbers just keep getting bigger and bigger and bigger
