Find a wien constant A from the equation [tex] R(\lambda,T) = \frac{2\pi h c^2}{\lambda^3} \frac{1}{e^\frac{hv}{kT} - 1} [/tex] Show that the Wien constant w = Lambda T = hc / 4.965k(adsbygoogle = window.adsbygoogle || []).push({});

Also i know that w = 2898 micro metres Kelvin

I'm not sure what to do here... Do i fiddle with the equation for hte spectral radiancy?? Do i expand the tern for the exp function?

But how would you manage to get the Boltzmann constant in the denominator without expanding the exp function?

Please do help with this!

Part 2 of this question is

Substitute numerical values for the constants and evalute. Compare the result with the Equation of w = 2898 [tex] \mu m K [/tex]

Now i need to solve the first part to get this second part, i would really really appreciate your help on this matter!!

Thank you in advance for this!
