Suppose a star with a radius 8.5*108 has a peakwavelngth of 688 nm in the spectrum of its emitted radiation.
(a) Find the energy of a photon with this wavelength
(b) What is the surface temperature of the star
(c) At what rate is energy emitted from the star in the form ofradiation? Assume the star is a blackbody (e=1)
(d) using the answer to part (a), estimate the rate at whichphotons leave the surface of the star.
