A sample of a crystalline solid scatters...

A sample of a crystalline solid scatters a beam of X-rays of wavelength `70.93` pm at an angle `2 theta` of `14.66^(@)`. If this is a second-order reflection `(n = 2),` calculate the distance between the parallel planers of atoms from which the scattered beam appears to have been reflected.

To solve the problem, we will use Bragg's Law, which is given by the equation: \[ n\lambda = 2d \sin \theta \] where: - \( n \) is the order of reflection, - \( \lambda \) is the wavelength of the X-rays, - \( d \) is the distance between the parallel planes of atoms, ...
