1.	For a crystal, the angle of diffraction (2q) is 90°and the second order line has a d value of 2.28 A.The wavelength (in Aº) of X-rays used for Bragg'sdiffraction is(a) 1.612(b) 2.00(c) 2.28(d) 4.00
Answer» EXPLANATION: ACCORDING to Bragg's EQUATION, $n \times <klux>WAVELENGTH</klux> = 2 \: d \: \sin( \alpha )$ $2x = 2 \times 2.28 {a}^{0}$ *Therefore* *the* *wavelength* of *Xray* *used* *will* be of *2.28A*

For a crystal, the angle of diffraction (2q) is 90°and the second order line has a d value of 2.28 A.The wavelength (in Aº) of X-rays used for Bragg'sdiffraction is(a) 1.612(b) 2.00(c) 2.28(d) 4.00

Answer»

$n \times <klux>WAVELENGTH</klux> = 2 \: d \: \sin( \alpha )$

$2x = 2 \times 2.28 {a}^{0}$

Therefore the wavelength of Xray used will be of 2.28A
