The Sun Is A Star

Classical Mechanics Level 2

The sun is the star at the center of the solar system. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. Astronomers found that the frequency of the light from point A is greater than that from point B above. Which of the following statements is correct in this connection?

a) This phenomenon proves the fact that the sun rotates in the direction from point A to B. In other words, as viewed from the top, the sun rotates counter-clockwise.

b) The light from point A shows a Doppler blueshift effect, and the light from point B shows a redshift effect.

c) The magnitude of the increase or decrease in frequency by the Doppler effect at point C is greater than that at point B.
