Surface temperature of Sun is

The solar energy received by the Earth persquare metre per minute is 8.315 xx 10^(4)Jm^(-2)min^(-1) . If the radius of the Sun is 7.5 xx 10^(5) km and the distance of the Earth from the Sun is 1.5 xx10^(8) km, calculate the surface temperature of Sun. Assume the Sun as a perfect black body. Given that Stefen constanta sigma = 5.7 xx 10^(-8)Wm^(-2)K^(-4).

Luminosity of a distant star is 16000 times that of the Sun. If the surface temperature of the Sun is 5890 K, then find the surface temperature of the star.

Estimate the surface temperature of sun. Given for solar radiations, lambda_(m)=4753Å . ( b=2.89xx10^(-3) meter Kelvin)

Experimental investigations show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible region. Estimate the surface temperature of sun. Given Wein's constant b = 2.88xx10^(-3) mK

Experimental investigations show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible ragion. Estimate the surface temperature of sun. (Given Wien's constant b = 2.88 xx 10^(-3) m K ).

Experimental investigations show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible ragion. Estimate the surface temperature of sun. (Given Wien's constant b = 2.88 xx 10^(-3) m K ).
