Question

when an electron is an excited Mo atom fall from Lto K shell;an X ray is emitted. These X rays afe diffracted at angles of 7.75° by planes with a separation of 2.64 A. What is the difference in energy between K shell anf Lshell in Mo assuming a first-order diffraction ( sin7.75° = 0.1349)​
