The Fresnel Biprism
... fringes, whereas when the biprism is further away, there are a larger number of fringes with smaller spaces in between them. This can be explained due to the fact that when the biprism is further away, the light that enters the biprism does so at a more acute angle than when the biprism is closer. ...

... Because of the different shape of the concave lens, these incident rays are not converged to a point upon refraction through the lens. Rather, these incident rays diverge upon refracting through the lens. What does this mean? A concave lens can never produce a real image. Concave lenses produce ima ...

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.
