Calculate the black body temperature of the sun from th e following data :- Stefan's constant = 5.7xx10^(-8) Wm^(-2)K^(-4) . Solarconstant = 1500 W//M^(2). Radius of the sun = 7xx10^(8)m . Distance between sun and earth = 1.5xx10^(11) m.

Calculate the black body temperature of the sun from th e following da

1.	Calculate the black body temperature of the sun from th e following data :- Stefan's constant = 5.7xx10^(-8) Wm^(-2)K^(-4) . Solarconstant = 1500 W//M^(2). Radius of the sun = 7xx10^(8)m . Distance between sun and earth = 1.5xx10^(11) m.
Answer» SOLUTION :`sigma =5.7xx10^(-8)Wm^(-2)K^(4), S = W//m^(2) , R =7xx10^(8) m, r =1.5xx10^(11) m` `T = [(r/R)^(2)S_(0)/sigma]^(1//4) = [((1.5xx10^(11))/(7xx10^(8)))^(2)xx1500/(5.7xx10^(-8))]^(1/4)`= 5895 K
