Chapter 5: Problem 7

In Bragg's equation for diffraction of X-rays, \(n\) represents a) number of moles b) quantum number c) order of reflection d) Avogadro number

Short Answer

Expert verified
In Bragg's Equation, \(n\) represents the 'order of reflection'. So, the correct option is 'c) order of reflection'.

Step by step solution

01

Understanding Bragg's Equation

Bragg's Law or equation is given as \(n\lambda = 2d\sin\theta\), where: - \(\lambda\): is the wavelength of incident wave, - \(d\): is the distance between the planes in the atomic lattice, - \(\theta\): is the angle of incidence.This equation is used to determine the angles for coherent and incoherent scattering from a crystal lattice.
02

Understanding the Role of 'n' in Bragg's Equation

In Bragg's equation, \(n\) is an integer and it denotes the order of reflection or scatter. It represents the fact that reflections can occur not just from the first layer of atoms, but from deeper layers as well.
03

Matching the Option

Based on the understanding from Step 2, it becomes apparent that in Bragg's equation, \(n\) represents the 'order of reflection'. Hence, option 'c) order of reflection' is the correct answer.
