It is possible to detect Doppler shifts due to light on each side of a rapidly spinning star.Suppose it is seen that a nearby star,relatively stationary to us,is blueshifted in light on one side of the star and redshifted in the light from the other side.Suppose a star of radius 2.5 108 km has light shifted from 525 nm to 527 nm on one side and to 523 nm on the other.What is the rotational period of the star?
A) 34 h
B) 32 h
C) 24 h
D) 16 h
