Problem

While investigating blackbody spectra, a class plots

\lambda_{\max}

(in metres) on the y-axis against

1/T

(in

\text{K}^{-1}

) on the x-axis and finds the slope to be

2.92\times10^{-3}\,\text{m K}

. Which numerical value of the Wien’s displacement constant

b

should be quoted from this result? (a)

2.92\times10^{-4}\,\text{m K}

(b)

2.92\times10^{-3}\,\text{m K}

(c)

2.92\times10^{-2}\,\text{m K}

(d)

0.292\times10^{-3}\,\text{m K}
