I have a simple question that is that is E=3/2x K_{b}x T, where k_{b}is boltzmann constant.

I understand that this is involve 3 degree of freedom, but as i was reading through the forum, i come across 1 equation stating E=k_{b}x T. So is it true? and what application would this apply to?

And with regards to quantum physics, since kinetic energy= 1/2MV^{2}, and =3/2k_{b}T,

yet, λ=h/p=h/mv, where h is planck constand and p is momentum, and λ is wavelength.

Since λ=V/F, where v is velocity and F is frequency,

then this would mean that V/F=h/mv, and I would get hxF=mV^{2},

and since E=hxv, where E is energy, h is planck constant, and v is velocity,

would that mean that E=mV^{2}which I don't understand as I thought E was suppose to be 1/2mv^{2}, yet now the 1/2 has disappear.

Thanks a lot for the help, a bit confused with all the energy, frequency and wavelength.
