For first order X–ray diffraction if lattice constant is `3 xx 10^(–8)` cm and glancing angle is 30°, then the value of `lambda` will be :

In Bragg's X-rays diffraction studies , 100 pm has second - order diffraction at glancing angle of 30^(@) Its interplanar spacing will be

X rays of wavelength lambda = 0.134nm . Gave a first order diffraction from the surface of the crystal value was found to be 10.5^(@) , calculate the distance between the plane in the crystal.

First diffraction minima due to a single slit of width 1.0 xx 10^(-5)cm is at 30^(@) . The wavelength of light used is :

Silver crystallises in a face centred cubic lattice with all the atoms at the lattice points. The length of the edge of the unit cell as determined by X-ray diffraction studies is found to be 4.077xx10^(-8) cm. The density of silver is 10.5"g cm"^(-3) . Calculate the atomic mass of silver.
