For the single slit interference problem, the slit is assumed to be made of N equally spaced oscillators, these small oscillators(Huygens Wavelets) produce disturbances/waves(electric field vector) which propagate in all radial directions. The interference of these disturbances from each oscillator produces the Diffraction pattern ~ (Huygens-Fresnel ...

Huygens' principle is linear superposition of spherical wavelets, hence it can be applied to every single wavelet individually that taken together form the incident plane wave, i.e., the propagation is applied to its Fourier transform. After they have propagated through the glass (plastic) you can sum (integrate) again and you get the far-field behavior of ...

I guess you need blazed diffraction grating: You don't really need to design it - they are manufactured in volume for spectrum analyzers, for example here: http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=26 . You may also check tutorial there, and a mandatory wiki link: http://en.wikipedia.org/wiki/Blazed_grating

Light diffracts through any object but the wavelength must be greater when compared to the size of the object. In this case it is slits so.

I think I understand it a little better now so I decided to post my thought and obviously won't accept my own answer. My understanding is that A(k) is the space of wave vectors, however we know these only differ by direction not magnitude for the diffracted wavepacket (Rayleigh scattering). Therefore the function A(k) indicates the "spread" of the ...

Molecules of air are all around us all the time. If so, during daylight do rays from the sun diffract as it passes through molecules in the air? and if so is this diffraction negligible to be noticed? plus does this affect anything? While both diffraction and scattering refer to redirection, I think scattering is the better term here. The molecules in ...

Re: diffraction of light by molecules in the air. The distances between atoms in molecules is approximately $0.1 nm$ which is about $5000$ times smaller than the wavelength of visible light. For diffraction effects to occur the structure should have similar dimensions to the wavelength of light - in this case the molecules are just too small for ...

This looks like an interference pattern like the type created by a diffraction grating. Note that to the left and right there are little rainbows with the red outermost and then green and blue innermost. Also the further away from the centre the wider the rainbows get. These features are characteristic of diffraction grating type phenomena. Now here the ...
