The image above represents wavelength. To calculate wavelength using Bragg’s law, three essential parameters are needed and these parameters are Order of Reflection (n), Inter-atomic Spacing (d) and Angle of Diffraction (θ).
The formula for calculating wavelength using Bragg’s law:
λ = 2dsinθ/n
Where:
λ = Wavelength
n = Order of Reflection
d = Inter-atomic Spacing
θ = Angle of Diffraction
Given an example;
Find the wavelength when the order of reflection is 2, the inter-atomic spacing is 10 and the angle of diffraction is 12.
This implies that;
n = Order of Reflection = 2
d = Inter-atomic Spacing = 10
θ = Angle of Diffraction = 12
λ = 2dsinθ/n
λ = 2(10)sin(12°)/2
So, λ = 20(0.207)/2
λ = (4.158)/2
λ = 2.079
Therefore, the wavelength is 2.079 m.
