i have a doubt.... can someone please tell me where i am going wrong?(adsbygoogle = window.adsbygoogle || []).push({});

by Einsteins calculations, rest mass of photon or something moving with v=c has zero rest mass, else its mass at motion tends to infinity, which is not possible. NOW substituting this in de broglies wavelenght eqn,

lambda=h/mv

=h/mc (for photon moving with light speed)

=h/0*c (since rest mass of the photon is zero)

=infinity

but for no photon it is possible that wavelenght is infinite. please tell my mistake.
