Mirror and Lens Distance and Magnification Formula

The object in question is a mirror, and the distance from its center is referred to as the News Distance.
The total distance from the image to the center is also known as the total distance.
Negative distance is required when the direction is left from the center.
Focal length determines the direction in which the lens flattens.
The focal length can be negative if the object and image are formed in the same direction.
The lens's focus is determined by its flat front, with a positive focus on the left side.
Magnification is the ratio of the size of the image to the size of the object.
The magnification formula differs for lenses and mirrors, with no units for magnification.
The combination of lenses involves adding their focal lengths, with a specific formula for balance.
Converting focal length to meters is crucial for accurate calculations, with a formula for power calculation.
