A: The speed of light in vaccum doesn't depend on nature of the source, direction of propagation nature of the source, direction of propagation, motion of the source , or observer wavelength and intensity of the wave.
R: The speed of light in vaccum is a universal constant independent of all the factors listed and anything else.

Does the speed of light in vaccume depend upon relative motion between source and observer ?

Let us list some of the factors, which could possibly influence the speed of wave propagation : (i) nature of the source ii) direction of propagation (iii) motion of the source and/or observer iv) wavelength v) intensity of the wave On which of these factors, if any, does the speed of light in vacuum
