... As emphasized in Chapter 18, students’ ability to successfully use the thin-lens equation does not mean that they have an understanding of image formation. Thus it is important that, especially at first, examples and problems on the thin-lens equation are first preceded by graphical ray tracing. It ...

... The smaller the distance between the two specific objects that can be distinguished apart, the greater the resolution power of the microscope. Minimal distance between two objects = (0.612 X ) / NA The larger NA, the smaller the resolvable distance and hence, the more efficient the resolution power ...

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
