#### Solution Summary

It proves that De Broglie wavelength associated with a particle
having kinetic energy K which is not negligible compared to its
rest energy m_0 c^2 is equal to
lemda = [h/(m_0 K)^(1/2)](1 + K/2m_0 c^2)^(-1/2) .
The solution is given in detail.
This is mainly for showing the relation between the De Broglie wavelength
and kinetic energy of a particle.
