4 Two Binary Stars Star 1 And Star 2 In Figure 6 Are Orbiting Each Other On A Plane So That It Will Appear That One S 1 (45.4 KiB) Viewed 20 times

4. Two binary stars (star 1 and star 2)in Figure 6 are orbiting each other on a plane, so that it will appear that one star is moving towards and the other is receding from Earth. If the stars are not moving, the astronomer expects to see the stars' wavelengths to be 520nm. But, when looking at them with accurate instruments, he found out that star 1 has a wavelength of 517nm and star 2 has wavelength of 525nm. (a) Which stars is moving away (red shifted) and which one is moving closer (blue shifted) to Earth? (b) How fast each star is moving? Dua bintang binary (bintang I dan bintang 2) dalam Rajah 6 mengorbit satu sama lain atas satu satah, sehinggakan ia kelihatan seperti satu bintang bergerak mendekati dan yang satu lagi menjauhi Bumi. Sekiranya bintang-bintang itu tidak bergerak, ahli kaji bintang menjangka akan melihat jarak gelombang bintang-bintang adalah 520nm. Tetapi apabila melihat dengan alat yang jitu, dia mendapati bahawa bintang 1 mempunyai jarak gelombang 517nm dan bintang 2 mempunyai jarak gelombang 525nm. (a) Bintang manakah menjauhi (peralihan merah) dan bintang yang manakah mendekati (peralihan biru)Bumi? (b) Berapakah laju tiap-tiap bintang sedang bergerak? V1 To Earth 'com V2 Figure 6 Rajah 6
