Can you Solve this question with all the details?
It is question 3 if you open the website:http://www.physics.carleton.ca/~kalyniak/phys2604/Ass8_2009.pdf
3. This is similar to Thornton and Rex #5-19. In an electronscattering experiment, an intense reflected beam is found at = 280 for a crystal with an interatomic distance of 0.23nm . What is the lattice spacing of the planes responsible for thescattering? Assuming this is first order diffraction, what are thewavelength, momentum, total energy and kinetic energy of theincident electrons. (Use multiples of eV and eV/c for your energyand momentum units.)
Thanks

Thanks

Explanation / Answer

From the Bragg's law        2d sin = m The wavelength of the electron is               = (2d sin)/m Here d = 0.23*10-9m            = 28o               m =1 The momentum of the electron is              p = h/ The energy of the electron is                E = h2/(2m2) Substitute the values.
