Medium is of two type One is material medium and other one is non-material Material medium are air medium, water medium etc Non-material medium is vacuum or free space If material medium is essential for the propagation of the wave then that wave is named as mechanical wave. Example: sound waves If such a material medium is not a must then the wave is said to be Electro magentic wave. Example: Light waves.
"air", "water" "glass" - generically a medium.
Thermal power plantThe term for such a material is "medium". Thus the sound of talking is carried by the medium air. The ocean waves exist in the medium water. Light is carried by the medium space. The plural is media.
Sound disturbance is propagated by compressions and rarefactions through the air medium. Air is a material medium. If such a material medium is absent then sound waves cannot be propagated. These compressions and rarefactions confirm that the wave is of longitudinal in nature.

A transverse wave of light can travel through air or gas.
The very name "mechanical waves" indicate that these need badly a material medium such as air, water etc.
medium
Light can travel through anything. The amount of light that gets through the material will vary depending on the amount of atoms in the target material.
answ2. Treating a material (wall, glass, air) as a transmission line, much of the incident sound will be reflected at the interface between medium one and medium two. And a similar transmission loss when the sound is re-radiated from medium two into medium one again.The characteristics of the transmission medium (air, concrete, glass ..) are considered as those of spring and mass. If these are very different between the two materials (media) then there will be little transmission of sound.So a concrete wall will be a good sound insulator, whereas a fibrous material would not be.the vibrations that cause sound can't travel through the material
material and medium
its an easy question. you know sound needs material medium to propagate {or move} and the atoms in solids are bound more closely than air. and thus when sound travels its easy for its waves to propagate through solids as the atoms {material medium} are more close than in air and on the contrary the molecules {larger parts of atoms ,who serve as material medium } of air are losely bound and its a bit harder for the waves to travel from one point to another.
