When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
Sound is a kind of energy. It is the vibrational energy being propagated in the form of longitudinal waves. So sound is not a gas but it needs a gas or other medium to propagate in.
acoustic or sound energy is a kinetic form of energy sound waves can only be measured when they travel through a medium, eich means that they have some velocity and hence acoustic energy is kinetic energy.
Because the theory is that this is what the form is. If it were a longitudinal or compressional form (such as sound) it would need to travel through a medium of some sort to compress the particles of that medium. But electromagnetic radiation can travel even in a vacuum.
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing
The form of energy that needs a medium to travel is known as mechanical energy.For example sound needs a medium to travel,that's why sound can't travel in vacuum,light needs no medium to travel it is non mechanical form of energy.
A wave, by definition, is an oscillation propagating through a medium. So in order for a wave to move it needs a medium (ie. air, water, earth, etc.) and energy. In the case of light (ie. photons), which is a form of wave that can travel through a vacuum, the medium is the electromagnetic field.

No, you can not produce sound in a vacuum. Sound wave needs medium (for example air) to travel unlike electromagnetic wave which can travel through empty space.actually, sound wave does not propagate itself rather it needs a medium by which sound particle can transfer there energy from one place to other, so it seems like moving. for eg. when u throw a stone in water ,some ripples form in water they seems to moving but not. like this sound propagate. hence it requires medium

Light actually travels in waves.This is known to be true because there are only 3 ways that energy can be transferred. As you probably already know, light does not need a medium to travel through because it travels through space. Electromagnetic waves are the only form of energy transfer that do not require a medium to travel through.
Radiation energy
since the sound requires a medium to travel through. so the air is one of the medium for sound to travel. Therefore sound can travel through air.
in the form of electromagnetic waves.
