Question

how sound are propagated in a medium?give an example.​

Answer 1

Answer:

PLZ MARK AS BRAINLIEST!

Explanation:

A sound is produced by a vibrating body. When a body vibrates, it produces sound in the surrounding medium. The vibrations are transferred to the medium surrounding the sound source. When the vibrations propagate away from the source, they form a sound wave.

Answer 2

Sound is propagated in a medium in the following ways -

• As we know a sound is a form of energy produced by the vibration of particles in a medium.

• Let us understand using an example that is how sound waves are produced: In a drum rolling when we hit the drum with the help of drum sticks, the outer membrane of the drum vibrates up and down. Whenever the drum membrane moves up it compresses the air just above it, and when it moves down it expands the air just below it.

• This is the exact way how the sound is propagated.
• Sound always needs a material medium for its propagation like solid, liquid, gas, or any molecule to travel because the molecules of solid, liquid, and gases carry sound waves from one point to another.
• Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
