The wavelength of maximum energy distribution by a star A is 4500 Å at a temperature of 5000 K. Calculate the temperature of star B for which wavelength of maximum energy distribution is 8000 Å.

The total radiant energy per unit area, normal to the direction of incidence, received at a distance R from the centre of a star of radius r whose outer surface radiates as a black body at a temperature T K is given by (where sigma is Stefan's constant)
