1.	Similar to electron diffraction, neutron diffraction microscope is also used for the determination of the structure of molecules. If the wavelength used here is `800 p m`, calculate the characteristic velocity associated with the neutron.
Answer» From de Broglie’s equation, `lambda = (h)/(mv)` `v = (h)/(mlambda)` Where, v = velocity of particle (neutron) h = Planck’s constant m = mass of particle (neutron) `lambda =` wavelength Substituting the values in the expression of velocity (v), `v = (6.626 xx 10^(-34) Js)/((1.67493 xx 10^(-27) kg)(800 xx 10^(-12) m))` `= 4.94 xx 10^(2) ms^(-1)` `v = 494 ms^(-1)` `:.` Velocity associated with the neutron `= 494 ms^(-1)`
