1.	Similar to electron diffraction, neutron diffraction microscope is also used for the determination of the structure of the molecules. If the wavelength used here is 800 pm, calculate the characteristic velocity associated with the neutron.
Answer» Solution :MASS of neutron `= 1.675 xx 10^(-27) KG` `lamda = (H)/(mv) or v = (h)/(m xx lamda) = (6.626 xx 10^(-34) kg m^(2) s^(-1))/(1.675 xx 10^(-27)kg xx (800 xx 10^(-12) m)) = 4.94 xx 10^(4) ms^(-1)`
