I made comparison between Doppler effect in light and sound and one interesting thing that I saw was that in the case of sound there are different formulas to find the apparent frequency in different situation (like observer moving,source moving,both moving etc) due to Doppler effect but in the case of light there is only one formula necessary to describe these situations.Why is it so?

My thoughts:I thinks it's a consequence of constancy of light speed in any reference frame.

Why same formula describing Doppler effect in the case of light in different situations?
