XRD analysis Why are diffraction gratings more realistic? - Diffraction by a Single Slit. The same relation holds in azimuthal plane ... Fraunhofer, Fresnel limits. See full discussion in the text book. Different parts of the slit have different distances to a given point on the screen, which causes interference effects.

How can we explain the pattern from light going, If we break up the single slit into a top half, The path difference between the top half and the, This is just like the double slit case, except, In fact, we can break the beam up into 2n pieces, For double slit, bright spots are equally, For single slit, central bright spot is larger, To have an appreciable q, d and w must be about, Recall that for small angles, sin(q) tan(q), If instead of a single SLIT, we have a CIRCULAR, the single slit pattern into a series of rings, Computer Homework CH 5-4 shows the rings in, Since the light seems to act like a wave and, How close can two points of light be to still be, The lens will focus the light to a fuzzy DOT, qlimit sin-1(1.22 l/D) and tan(qlimit) x, If a second point of light makes an angle of, qlimit with the first point, then it can just be, Consider the (ideal) resolving ability of the eye, Use l 550 nm (middle of visible spectrum), Now calculate the minimum angle the eye can, Now calculate how far apart two points of light, qlimit sin-1 (1.22 x 5.5 x 10-7 m/.005 m), Estimate how far it is from the lens of the eye, With your same D and l (and so same qlimit), now, How does this distance compare to the distance, s 2 cm (estimation of distance from lens to, from previous part, qlimit 7.7 x 10-3 degrees, Imperfections in the eye (correctable with, Rayleigh Criterion due to wavelength of visible, f-stops resolution resolution depends on D, microscopes smallest angle, qlimit, is limited, can reduce l by immersing in oil, use blue light, Light from far away is almost parallel.
