Focal length is the distance between the lens or mirror and its focus, where parallel rays of light converge. It determines the magnification and field of view of optical systems, influencing how images are captured and perceived in photography and optics.

Magnification is the process of enlarging the appearance of an object through optical instruments such as lenses or microscopes, allowing for detailed examination and analysis. It is crucial in scientific fields like biology and astronomy, where it aids in observing minute details and distant celestial bodies.

Field of view refers to the extent of the observable world that can be seen at any given moment through an optical instrument or the human eye. It is crucial in applications like photography, astronomy, and virtual reality, where it influences perception and spatial awareness.

Optical systems are assemblies of lenses, mirrors, and other optical elements designed to manipulate light to achieve specific functions such as imaging, focusing, or directing light beams. They are fundamental in various fields, from everyday devices like cameras and eyeglasses to advanced technologies in scientific research and telecommunications.
