Vedclass · Answer

(C) The sun rotates about its axis from west to east. Due to this rotation,one end of the sun's equator moves towards the earth,while the opposite end moves away from the earth.According to the Doppler effect for light,when a source moves towards an observer,the frequency of the emitted light increases,causing a shift towards the violet end of the spectrum (blue shift).Conversely,when a source moves away from an observer,the frequency decreases,causing a shift towards the red end of the spectrum (red shift).Therefore,for an observer on the earth,the spectral lines from the end moving towards the earth will shift towards the violet end,and the spectral lines from the end moving away will shift towards the red end.

The sun is rotating about its own axis. The spectral lines emitted from the two ends of its equator,for an observer on the earth,will show
