Optics - Tensors for Tots
... Every point of a wave front can be considered the origin of a new circular or spherical wave, the so-called elemetary wave. The new position of the wave front results from the superposition of all of the elementary waves. The Huygens wave front is a series of concentric circles originating from the ...

... Dispersion, the variation of the index of refraction with frequency in transparent materials, causes problems with the focal properties of lenses. As we saw, in prisms, blue light bends more than red light. So the same effect must happen in lenses—where one assumes that ray paths are independent of ...

... Solution: We learned that when thin lenses are put next to one another the total focal length is found from 1/ f = 1/ f1 + 1/ f 2 . This gives the values shown. You can also work it out manually. If an object is placed a distance p from f1, then the image location q is found from 1/q = 1/ f1 "1/ p . ...

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.
