Mechanical waves may travel through any medium except vacuum.
Sound is a mechanical wave, and mechanical waves need something to travel through.
Mechanical waves, shock waves, etc.
Mechanical waves must use matter as a medium, they displace the matter in space. Examples of mechanical waves are sound waves (must go through gas (air) which is matter), ocean waves (must go through liquid (water) which is matter, and earthquakes (must go through solid (earth) which is matter.Electromagnetic waves do not need matter as a medium and are made of electromagnetic radiation, they cause fluctuations in the magnetic and electric fields that permeate space-time. Examples of electromagnetic waves are radio waves, microwaves, x-rays, and gamma rays (all are part of the electromagnetic spectrum or EMS).
Non mechanical waves are Eletro magnetic waves. We can devide 2 waves. 1 is mechanical waves & 2 is electromagnetic waves. For example Sound is a mechanical wave & Light is an electromagnetic wave.
Sound is mechanical energy. It's a vibration or oscillation, and it is transmitted as a wave of pressure and displacement. Like all mechanical waves, sound requires a medium through which to travel, and the source transfers mechanical energy into the medium. Solids and fluids (liquids or gasses) serve as mediums for the transmission of sound waves.
Mechanical waves may travel through any medium except vacuum.
A dish antenna must face the arriving waves.
A dish antenna must face the arriving waves.
Disturbances that transfer energy, or waves. Mechanical waves must have a medium to travel.
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .

When a wave passes through a substance, it gets transmitted through it. The speed of the wave changes depending on the nature of the substance.
Mechanical waves require a medium while Electromagnetic waves does not.
S-waves are not transmitted through the outer core.
