Question

4) Consider the following image: 00 min 07 OB Relative Flux P 03 03 OR Rest Wavelength Hy = 434,1 mm 400 20 CS Wavelength (nm) a. Given that the rest wavelength means the wavelength measured in the laboratory (where the low point would be expected), what can be said about the red and blue data lines shown? b. How is the assumption that the laws of physics are the same everywhere in the Universe relevant here? c. Why does this suggest a binary star system?

Answer 1

(a) identical we can see that the lines are at same us and hence while in and increased). so we can From the graph That is the emission (apsorption is happening wave length in the atmosphere of the system. But these two are shifted from each other hence it will blee-shift and red shift. In blive shift the object is moving towards increase in frequency of light red shift, the object is moving away from us frequency detected gol decreased for wavelength see that the same light with rest wavelength Hy= = 434.1 nm is bluel sleifted and Red sleifled. shift in wavelength Paboratory also observing the same kind of shift in this system plapsics. say laws of physics applies everywhere. binary system is a combination of two stars. Orbiting each other. When a dectector defects light. One of the Star A is moving away from detector hence RED shift in light and other moving towards the detector hence blue shift in light. This is the thing we seeing in the graphe. Hence we can say that it is a in our سی As we can Create we are so we can that by using same Same © А Detector عليا Sinary system.
