An x-ray beam with wavelength 0.240 nm is directed at a crystal. as the angle of incidence increases, you observe the first stro
ng interference maximum at an angle 24.5 ∘. what is the spacing d between the planes of the crystal?
1 answer:
This phenomenon is called the Bragg scattering. The working equation used for this is:
λ = 2dsinθ
where
λ is the wavelength and θ is the incident angle
0.240nm = 2dsin(24.5°)
Solving for d,
<em>d = 0.29 nm</em>
