PrevPreviousIf the angle of incidence of X-ray of wavelength 3 Å which produces a second order diffracted beam from the (100) plane in a simple cubic lattice with interlayer spacing a = 6 Å is 30°, the angle of incidence that produce a first order diffracted beam from the (200) planes is

NextWhen an electron in an excited Mo atom fall from L to K shell; an X- ray is emitted. These X-rays are diffracted at angles of 7.75° by planes with a separation ofNext
