Suppose a star with radius 8.61 108 m has a peak wavelength of 686 nm in the spectrum of its emitted radiation.
(a) Find the energy of a photon with this wavelength.
J/photon
(b) What is the surface temperature of the star?
K
(c) At what rate is energy emitted from the star in the form of radiation? Assume the star is a blackbody (e = 1).
W
(d) Using the answer to part (a), estimate the rate at which photons leave the surface of the star.
