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 a medium (say, glass or water), depend ?

Explanation

Dependence of the speed of light in a medium
i) Does not depend on the nature of the source.
ii) Independent of the direction of propagation for isotropic media.
iii)Independent of the motion of the source relative to the medium but depends on the motion of the observer relative to the medium.
iv) Depends on wavelength.
v) Independent of intensity.
