Your x-ray lab has a monochromator consisting of a single crystal of nickel cut so that the (001) plane lies in the cube face. At what angle (in degrees) should the cube face be tilted with respect to the incident beam in order to select radiation with a wavelength λ=3.091 A˚? The lattice constant of nickel is a=3.53 A˚.

Your x-ray lab has a monochromator consisting of a single crystal of nickel cut so that the (111) plane lies in the cube face. At what angle (in degrees) should the cube face be tilted with respect to the incident beam in order to select radiation with a wavelength λ=3.091 A˚? The lattice constant of nickel is a=3.53 A˚.

plzzz help

d111
λ=3.091A
a=3.53A

λ=2d(111)Sin(angle)
d=a/sqrt(h^2+k^2+l^2)
