Question
Pad * 73% 1:25 PM instructure-uploads,s3.amazonaws.com Blackbody Radiation 61 9) Two students are discussing their answers to Question 8 Studen: Star E looks redder because it is giving off more red light than Star F Student 2: I disagree, you're ignoring how much blue light Star E gives off Star E gives off more blue light than red light, so it looks bluish. Star F gives off more red than blue, so it looks reddish. That's why Star F looks redder than Star E Do you agree or disagree with either or both of the students? Explain your reasoning 10) Using the blackbody curves shown in Figure 2b, for each characteristic listed in the table below circle the correct response in the column to the right. Characteristic Peaks at a longerStar E Star C They peak at the same wavelength wavelength Has a lower surface Star E Star C They have the same surface temperature temperature Looks red Looks blue Has a greater energy Star E Star C The have the same energy output output Responses Star E Star E StarC Star C They both look red They both look blue Neither looks red Neither looks blue 11) How must Star C be different from Star E to account for their difference in energy output? Explain your reasoning 12) Two students are discussing their answers to Question 11 Student 1: The peaks are at the same place so they must be at the same temperature. If Star C were as big as Star E, it would have the same output. Since the output is lower, Star C must be smaller No. If its output is lower, it must be cooler. Since the temperatures of the two stars are the same, they must be the same size Student 2: Do you agree or disagree with either or both of the students?

Question 9:
I disagree to the both students. The color of star depends on the peak of spectrum and temperature of star. All star emits visible light of all colors to some degree. It’s just that their spectrum peaks at a particular color. So if the Star E spectrum peaks at red light wavelength then it will look red and if it peaks at blue light wavelength then it will look blue, same goes for Star F.
If it observed that the red stars are more cooler than the blue star.
