de Broglie's eqn. proof goes this way:---(adsbygoogle = window.adsbygoogle || []).push({});

E = m*c^{2}

E = h*c/L (L - Wavelength)

the they are equated -

m*c^{2}=h*c/L

=> L=h/(m*c)

But in E=m*c^2, m is the mass lost by some body to give energy E not mass of photon,

then why do we consider m mass of photon ??

By considering that we find equivalent eqn.--

L=h/(m*v)

for any mass m.

Isn't that wrong??
