Because th Sun rotates on its axis,one edge of Sun moves toward Earth and the other moves away.The Sun rotates approximately once every 25 days,and the diameter of the Sun is 1.4*10^9m.Hydrogen on the Sun emits light of frequency 6.16*10^14Hz from the two sides of the Sun.What changes in the wavelengh are observed?
太阳两端相对地球的速度差
波长的改动=c/v=c/w*r=c/ 2π/(25*24*360000 ×1.4*10^9/2=3.3*10^-12m如果我的v用的是r/t
则我得到:v=1/2*1.4*10^9/(25*24*360000/4)
这样算的话我哪里做错了?显然你错了。太阳是球体,取得速度当然是切线速度倘若取的是切线速度,那么one edge在离我们最远时,是直线指向我们的,在离我们最近时,是...

波长的改动=c/v=c/w*r=c/ 2π/(25*24*360000 ×1.4*10^9/2=3.3*10^-12m
