Electron has wave rature as well as particle nature

What is the relation between wave nature and particle nature of moving particles?

Explain how an electron can be considered to have a particle as well as a wave nature. Using Planck's equation, E=hv and Einstein's equation E=mc^(2) , deduce de Broglie relation for a photon.
