What is the formula for Bragg's Law?

41. What is the formula for Bragg's Law?

1. d sin θ = nλ
2. 2d sin θ = 2n^λ
3. 2d sin θ = nλ
4. 2d sin θ = n²λ

Answer

The correct answer is: C) 2d sin θ = nλ

Explanation

Bragg's law is expressed as: 2dsinθ=nλ

Where:

• d is the spacing between crystal lattice planes.
• θ is the angle of incidence of the X-ray beam.
• n is an integer representing the order of the diffraction, and
• λ is the wavelength of the x-ray.
