"The speed of light remains constant in a transparent homogeneous medium". Justify this statement and also explain the meaning of homogeneous in the statement. Share with your friends Share 1 Mahak Jain answered this Dear student,A homogeneous medium is one whose refractive index is same all over the space of medium. refractive index=speed of light in vacuumspeed of light in that mediumWhenever there are two media interface the light rays undergo in refraction but the extent of refraction depends upon the refractive index of the two media. So in a transparent medium of heterogeneous composition due to variable refractive index refraction of light occurs.Hence the speed of light does not remain constant and changes according to the refractive index of that transparent mediumRegards 1 View Full Answer
