When an electron in an excieted 'Mo'atom falls from 'L' to 'K' shell , an X-ray is emitted.... These X-rays are diffracted at one angle of `7.75^(@)` by planes with a separation of `2.64A^(@)`. What is the difference its energy between K-shell and L-shell in 'Mo' assuming a first order diffraction.
