Okay, so I know that Planck's Law states that,(adsbygoogle = window.adsbygoogle || []).push({});

u(v) dv = 8[tex]\pi[/tex] v[tex]^{}3[/tex] / c[tex]^{}3([/tex]e[tex]^{}(hc/kT)[/tex]-1)

to make this formula in terms of wavelength, do you just plug in c = v[tex]\lambda[/tex], or is there more to it? because what I get is not what I find on the net to be correct.
