Question

assuming that the temperature at the surface of the sun is 6000K find out the size of virtual star ​

Answer 1

Answer:

Correct option is

C

7500K

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
