Problem

For two different perfectly black bodies, the following data are obtained: (i)

\lambda_{\max}=450\,\text{nm}

when

T=6450\,\text{K}

(ii)

\lambda_{\max}=2.9\,\mu\text{m}

when

T=1000\,\text{K}

(a) Calculate the product

\lambda_{\max}T

for each case. (b) State whether the results support the existence of a universal constant value for this product and give a brief reason.
