Sound travels in a medium means
Answers
it is a longitudinal wave hence requires material medium fr transfer..... it also means tat sound can nly travel thru solid liquid ans gases bt nt thru vaccum
The medium of sound is any basic matter that is densely packed enough for its atoms or molecules to easily and consistently “hit” (significantly influence electromagnetically) one another in large enough numbers to carry a coherent wave of pressure.
This would be solid, liquid, gas, plasma, and I’m not sure but I would guess even antimatter, etc. too, why not? If, however, the density drops too low, then a lot of the particles will get knocked around, but have nothing near them to pass the knock along to, and the wave will fall apart / the sound integrity will drop over a very short distance.
