What is the formula for Bragg's Law?
41. What is the formula for Bragg's Law?
- d sin θ = nλ
- 2d sin θ = 2nλ
- 2d sin θ = nλ
- 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.
