Imagine that you are observing a star and you find the wavelength of peak emission for the star to be 400 nm. What would the wavelength of peak emission be for a new star that has a surface temperature that is a quarter of the original star? • Using the same pair of stars from the first question, how does the luminosity (the energy output) of each star compare if we assume that both stars are the same size? (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 snooking
