Solution
According to De Broglie hypothesisp=hλ =6
62×10-341×10-9 = 6
62×10-25 kg 
m/sThe value remains same irrespective of electron or photon
Energy of photon and electronE = pc =6
62×10-25 ×3×108 =19
86×10-17 JKinetic energy of electronK E
 =p22m =6 62×10-25 ×6
62×10-25 2×9 1×10-31 =2
41×10-19   J
