face of the sun to the temperature at the
centre of the sun is -
(1) 58: 1500 (2) 29:75000
(3) 1:1
(4) 1:100​

Answer 1

Answer:

By Wein's Displacement law at the maximum intensity:

⇒λ

1

T

1

=λ

2

T

2

where, λ

1

is the wavelength at T

1

and λ

2

is the wavelength at T

2

⇒500×6000=400×T

2

⇒T

2

=7500K
