Assertion : X - rays cannot be diffracted by means of grating . Reason : X - rays does not obey Bragg's law.

what is diffraction due to ?

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.

A diffraction grating is ruled with 600 lines per millimetre. When monochromatic light falls normally on the grating, the first order diffracted beams are observed on the far side of the grating each making an angle of 15^@ with the normal to the grating. What is the frequency of the light?

Calculate the angle at which first order reflection will occur in an X-ray spectrometer when X-rays of wavelength 1.54Å are diffracted by the atoms of a crystal given that interplanar distance is 0.04Å .

It is desired to obtain a diffraction pattern for electrons using a diffraction grating with lines separated by 10 nm. The mass of an electron is 9.11 xx 10^(-31)kg. What is the approximate kinetic energy of electrons that would be diffracted by such a grating?
