Suppose a star with radius 8.50 _ 108 m has a peak
Chapter 27, Problem 27.30(choose chapter or problem)
Suppose a star with radius 8.50 _ 108 m has a peak wavelength of 685 nm in the spectrum of its emitted radiation. (a) Find the energy of a photon with this wavelength. (b) What is surface temperature of the star? (c) At what rate is energy emitted from the star in the form of radiation? Assume the star is a blackbody (e _ 1). (d) Using the answer to part (a), estimate the rate at which photons leave the surface of the star.
