👉 Prescision, in mathematics and physics, is a measure of how closely a quantity or object is measured to be exactly equal. It can be defined as the minimum distance between two points on an object's surface that are within a certain tolerance level. In the context of optics, precision refers to the accuracy with which an object is observed at a given distance from a source. It is important in fields such as astronomy and physics where precise measurements are crucial for determining the shape, size, orientation, and
