Problem 2: X-ray diffraction: (a) Determine the maximum wavelength for which constructive interference can be observed in the Bragg model for a simple cubic crystal with a lattice constant of 3.6 A. (b)What is the energy of the X-rays in electron volts? (c) If you were to perform neutron diffraction, what would the energy of the neutrons have to be in order to obtain the same de Broglie wavelength? (d) You could argue that if you take X-rays with twice...
Answer ALL parts to this question: In X-ray diffraction, when parallel beams of X-rays are applied to a sample, describe what processes may occur. You can use a diagram to help explain your answer. With the use of a diagram, explain how Bragg’s law is applied to analyse a crystalline sample. With the use of diagrams describe and explain what differences you would note on the X-ray Diffraction plot of an amorphous, crystalline and semi-crystalline polymer. How do these relate...
*thermal expansion of metal 1)we can assume that lattice of solid follows simple harmonic motion. how can we explain thermal expansion of solid? explain please (hint:consider statistical fact that as T goes up,the probability to have state of higer level quantimisation goes up.so consider <x> ) b)draw potential(U=U(x)) so as to be stretched as temperature goes up in accordance with experiemét situation. and write simple mathematical form
2. Coefficient of thermal expansion (CTE), ay by volume is approximately three times of linear CTE, at ay of fused silica and silicon carbide is 1.65 x 10-6/°C and 12.9 x 10-6/°C, respectively.
