Determine the expected diffraction angle for the first-order reflection from the (310) set of planes for bcc chromium when monochromatic radiation of wavelength 0.0735 nm is used. the atomic radius for cr is 0.1249 nm.

Answer :

Explanation :

It is given that,

Wavelength,

According to bragg's law:

d is inter planer spacing for (310) planes such that :

a is lattice parameter,

R is atomic radius and for BCC

So,

Hence, this is the required solution.

50 inches should be the resultant vector

be subject to a force andchange its motion
