    X-ray diffraction; atomic form factor

    Hey! Can u explain how did you calculate the form factor? I don't know how to pass from the vectoric experession to an expression I'll be able to calculate.. tnx a lot!

    How Does Atmospheric Refraction Affect the Visibility of a Duck in a Desert?

    Thanks for your help & advices. :) What do you mean by hyperbolic trig substitution? The integral result is logarithmic, isn't it?

    How Does Atmospheric Refraction Affect the Visibility of a Duck in a Desert?

    Homework Statement A duck is walking in a flat desert (yes, the proff. is creative...). According to atmospheric conditions the Refractive index is n(y)=1.0006-0.0003y. y in KM. An observer is on the ground, 26.2 KM far. Where will he see the duck? Show the gragh of the ray path...

    Diffraction through a ring aparture

    Homework Statement 1.compute the diffraction pattern through a ring aparture, internal radius a, external radius b, wave length lambda. the incoming wave is a monochromatic, plane wave, vertical to the ring plane. 2.how will the diffraction expression change when a->b? 3.near the aparture...
