Small focal length vs large focal length
WebbThe convex lens that is close to the object is known as objective lens and the lens placed near to the eye is known as eye piece. Objective lens has small focal length and small aperture because for small focal length it is necessary to have small aperture. Solve any question of Ray Optics and Optical Instrument with:- Patterns of problems > WebbChanging perspective can make objects appear smaller or larger than normal. A shorter focal length will give images an expanded appearance and make objects appear larger, …
