A beam of neutrons with a de Broglie wavelength of 0.231 nm diffracts from a crystal of table salt, which has an interionic spacing of 0.282 nm
What is the angle of the first interference maximum? __________ degrees
From the bragg's diffraction formula
2 d sin theat = n L
2(0.282 nm) sin theta = 1(0.231 nm )
theat = sin ^-1 (1(0.231 nm )/2(0.282 nm)) = 24.17 degree
n = 1
we have d*sin(A) = n*lamda
0.282*10^-9*sin(A)= 1*0.231*10^-9
sin(A) = 0.231/0.282
A = 54.999 degrees

Problem 1 (Electron Beam Diffraction/De Broglie Wavelength): A beam of 125-eV electrons is scattered from a crystal in an X-ray diffraction experiment, and a first- order peak is observed an angle of 38 from the normal to surface of the crystal. What is the spacing between planes in the diffracting crystal? can you please show steps in solving this problem
When an x-ray beam is scattered off the planes of a crystal, the scattered beam creates an interference pattern. This phenomenon is called Bragg scattering. For an observer to measure an interference maximum, two conditions have to be satisfied: a). An x-ray beam with wavelength 0.120 nm is directed at a crystal. As the angle of incidence increases, you observe the first strong interference maximum at an angle 23.0 ∘. What is the spacing d between the planes of the...

A) If the De Broglie wavelength of an electron is equal to 350 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. B) If the kinetic energy of an electron is 440 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron.
