If the intensity of the Sun peaks in the optical range, at a frequency of about 3:4 x 10 Hz, what is the temperature of the Sun? Use the Wien displacement law (1.25). If all of the power is emitted only between 3 and 4 x 10 Hz, how many photons per cm² arrive at the earth when the Sun is directly overhead? What is the power received on earth per cm³? A value for the solar power is 135mW per cm². How does this compare to your calculation?

Imagine that you are observing a star and you find the wavelength of peak emission for the star to be 400 nm.

(Please provide a specific factor or proportion) What type of radiation/light (from the electromagnetic spectrum) is each star emitting? Now imagine that we determine that the wavelength of peak emission of the original star was determined to be bluer than it should be based on other observations. Would this indicate that the star is moving towards us or away from us relatively speaking through space? (Hint: think of the Doppler effect)
