For a crystal, the angle of diffraction (2 ) is 90^ and the second order line has a d value of 2.28 Ã… . The wavelength (in Ã… ) of X-rays used for Bragg's diffraction is

Step-by-step solution

Given, angle of diffraction (2 )=90^ =45^ Distance between two planes, d=2.28 Ã… n=2 [ second order diffraction ] Bragg's equation is aligned n & =2 d 2 & =2 2.28 45^ & =1.612 aligned
