Chapter 37: 37.2 Q6. (page 1081)

What temperature, in °C, is a blackbody whose emission spectrum peaks at (a) $300 n m$ and (b) $3.00 m m$ ?

Short Answer

Expert verified

(a) $9393.67 ° C$ (b) $693.67 ° C$

Step by step solution

(a) Given λ=300nm Now, We simply need to apply wien's displacement law :-

$λ (n m) = 2.9 x 10^{6} (n m . k) \frac{}{} T$

$T = \frac{2.9 x 10^{6} (n m . K)}{λ (n m)}$

width="196" height="28" role="math">T=2.9x106(nm.K)300 ( $λ$ = $300$ )

$T = 300 T = 9666.67 K = 9393.67 ° C$

(b) Given λ=3.00mm Again applying wein's displacement law :-

T = \frac{2.9 x 10^{6} (n m . K)}{300} T = 966.67 K T = 693.67 ° C

(λ = 3.00 m m)
