Question

stars generate a spectra that behave to a good approximation as ideal blackbodies. the star X has the max of its spectral radiant emittance at wavelength lambda=292nm. its photosphere has a radius of 1.19*10^9m.

a. compute the temperature of the surface of star X

b. compute the total radiant emittance of star X at this temperature

c. compute the total power radiated by star X

d. compute the energy of a photon at wavelength lambda(max) in eV
