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 pm, calculate the characteristic velocity associated with the neutron.
Mass of neutron = 1.675 x10-27 kg
We know λ = h/mv
or
v = h/mλ
Substituting the value ,we get
6.626x10-34 / (1.675x10-27)(800x10-12)
= 4.94x104 m/sec
