At school, I am taught that the "derivation" of de Brogle wavelength of a matter wave is as follows.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]E=mc^2, E= h\nu[/tex]

So

[tex]mc^2=h\nu[/tex]

Then setting c=v by analogy derive the exp. for de Broglie wavelength.

Here's the problem, I can't understand in what context the two energies are equated.

I only know that the first eqn is mass energy equ. and the second eqn. is energy of a discrete photon.So obviously m must be the mass of photon

right? Now is this mass the rest mass of photon ? I don't even know much about SR other than the basic postulates.

Also what is the exact nature of matter waves?

Do they transport energy or are they probability functions?

Is it possible to approximate how much of a system is wave like and and how much of it is particle like ?

I don't think it is really right to deal with these topics before SR as they do in my syllabus. What do you think?

Thanks in advance for the replies.Any links will also be appreciated.
