Question

what is the relation of binocular with physics ​

Answer 1

Binoculars are simply two telescopes side by side, one for each eye. But there's a catch. When light rays from a distant object pass through a convex lens, they cross over. That's why distant things sometimes look upside down if you look at them through a magnifying glass.
