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 associted with the neutran.

Explanation

`lambda=h/(mv)`
or `v=h/(mxxlambda)`
`(6.626xx10^(-34) kgm^(2) s^(-1))/(1.675xx10^(-27)kgxx(800xx10^(-12)m))`
`=4.94xx10^(4) m s^(-1)`
