The light did not need any medium,then why light is consider under transitional wave motion that required material medium?

We know that light doesn’t need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.
Light contrasts with sound, which travels through the air (or some other material medium). If you’re stationary with respect to the air, then the speed of sound is the same in all directions. But if you’re moving with respect to the air, the speed of sound will be the same in all directions relative to the air—which means that sound coming up in front of you will seem faster and sound catching up to you from behind will seem slower.
If light were a disturbance in a medium, it would exhibit the same behavior. But light never does—its speed is the same under all circumstances. So it does you no good to postulate an aether. You can still do it, but it makes the theory more complicated than necessary. The only reason to postulate an aether is that you’re uncomfortable with the idea of waves not needing a medium. But our modern understanding of quantum mechanics is that all kinds of particles have a wavelike nature, so, if you accept that matter can travel through empty space, you should have no problem accepting the same for light.

Thanks for your answer.But i think that it will grouped by the propagation.
please mark it as Brainlist answer

First of all Ur question is wrong. Light is not a particle that it would require any material medium for its propagation. Secondly, light travels in bundles of energy known as photons and photons are not particles.
but transverse wave require a medium and wave has particle ,then why light consider under this catagory?
