In the form of longitudinal waves
Vibration of air molecules produces sound waves. These waves are propagated through the air as differences in pressure, which our ears can detect as sound.
It propagates by the to and fro motion of air particles along the direction of wave propagation. Compressions (regions of high air density and pressure) and rarefactions (regions of low air density and pressure) are set-up in the process. Its propagation is aided due to the fact that sound can diffract through very large angles. This is due to the large wavelength of the sound waves.
Yes, a sound wave is a mechanical wave. Sound waves need a medium (like air) to travel through. The energy of the wave, the mechanical energy, is transferred into the medium through which it is propagated.
No. Sound requires a medium to propagate through
When you hit it, the triangle vibrates, and the air around it vibrates. The air particles closest to it vibrates, then the air particles next to the first ones start vibrating as well and so on, so it reaches your ear. From liam514 if u have any other questions tell me and i will answer them as best as i can.
Vacuum as sound needs badly a material medium to get it propagated.
Because there are no enough molecules in empty space for sound to be propagated.
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.
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.
radio waves are propagated through the interaction of
Sound travels from one place to another as a result of vibrations. When an object or a source of sound such as a speaker vibrates, it creates compressions and rarefactions in the surrounding medium, usually air. These compressions and rarefactions are propagated as waves, which travel through the air and reach our ears, allowing us to perceive the sound.
A group of atoms move, bump into the next group of atoms, etc.; the energy of the bumping gets propagated. Sound will travel through almost any material.
