= 2(6.00X10

v = 3.629X10

Now using deBroglie's equation:

l = h/mv = 6.63X10^{-34}/(9.11X10^{-31}
X 3.629X10^{4})

= 2.005X10^{-8} m

Now using Planck's equation:

E = hc/l = 6.63X10^{-34} X 3X10^{8}/2.005X10^{-8}

= 9.92X10^{-18} J

Now, would you like to see a more elegant and shorter solution?
