1.

If intensity (I) versus wavelength (λ) for three identical black bodies at temperature T1, T2 and T3 are shown in figure, then

Answer»

We know that emissive power is 

E \(\propto\) T4

According wein's displacement law

\(\lambda_{max}T = constant\)

T \(\propto\) \(\frac1{\lambda_{max}}\)

So, We can say

T1 > T2 > T3
