Question

If Wien's constant b=0.3cm K , then the temperature of the Sun having a maximum intensity of radiation at 5000Å wavelength is (A) 5000 K (B) 6000 K (C) 4000 K (D) 7000 K

From Wein's displacement law λ mT=b 5000× 10- 10× T=0.3× 10- 2 T=6000 K

Q. If Wien's constant $b = 0.3 c m K$ , then the temperature of the Sun having a maximum intensity of radiation at $5000Å$ wavelength is

$5000 K$

$6000 K$

$4000 K$

$7000 K$

From Wein's displacement law
$λ_{m} T = b$
$5000 \times 1 0^{- 10} \times T = 0.3 \times 1 0^{- 2}$
$T = 6000 K$

Q. If Wien's constant b=0.3cmK , then the temperature of the Sun having a maximum intensity of radiation at 5000Å wavelength is

5000K

6000K

4000K

7000K
