Question

The maximum gadiant power of sun is at
wavelength sooom. The wien displacement law
constant is 2.89 8 X 1013 mk. Assuming the sun
to be a black body hadiator , the temperature
of Sun is​

Answer 1

Answer: Given : λ

m

​

=470nm=4.70×10

−7

m b=2.898×10

−3

mK

From Wien's displacement law, Tλ

m

​

=b

We get, temperature of sun T=

λ

m

​

b

​

∴ T=

4.70×10

−7

2.898×10

−3

​

=6166
