Suppose a star with radius 8.67 108 m has a peak wavelength of 684 nm in the spectrum of its emitted radiation. (a) find the energy of a photon with this wavelength. 2.908e-19 correct: your answer is correct. j/photon (b) what is the surface temperature of the star? 4237 correct: your answer is correct. k (c) at what rate is energy emitted from the star in the form of radiation? assume the star is a blackbody (e = 1). 1.827e7 incorrect: your answer is incorrect. your response differs significantly from the correct answer.
