Monochromatic X-rays having a wave length of 10.4A are preferentially diffracted by a crystal at an angle 25.5°, assuming that this is the first order diffraction with a d-spacing between crystalline planes equal to 12.1 A. What is the value of sin 6 for the second order diffraction? (a) 0.959 Assion the Bravais lattice tvne for the following unit-cell stucture (b) 0.759 (c) 0.859 (d) 0.659

    1/2=sin25.5/sin θ2 sin θ2 = 2×0.43 sin  θ2= 0.86
