i have a doubt... can someone please tell me where i am going wrong?
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.
