... The Fraunhofer diffraction pattern from two microscopic circular holes separated by a distance d is observed at a wavelength of 500 nm on a screen placed 50 cm from the aperture plane. Inspection of the pattern shows that it is at the Rayleigh limit of resolution (i.e. the principal maximum appears ...

... Questions 6,7,8, and 9 address various topics. The layout of the questions can be a bit confusing. They don’t label parts of questions (a) (b) (c) etc so it is necessary to read carefully and ensure that you attempt each part. I generally advise my students to put a line through each part when you h ...

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.
