Question

X-ray beam of wavelength 2.9 AU is diffracted from the plane of cubic crystal. The first order diffraction is obtained at the angle of 35°. Calculate the spacing between the planes.​

Answer 1

Answer:

ANSWER

The Bragg’s Law of diffraction is given as

2dsinθ=nλ

By substituting the values given in the above equation we get

2×2.8×10
