Question

What is sound ?explain ?

Answer 1

⭐Sound is a vibration that propagates as an audible wave of pressure, through a transmission medium such as

➡ a gas,
➡liquid or
➡solid.


⭐Sound is actually the reception of such waves and their perception by the brain nervous system or neural network.


⭐They are created by the vibration of an object, which causes the air surrounding it to vibrate That is The pressure difference.

⭐The vibrating air or pressure difference between air particles ,then causes the human eardrum to vibrate which the brain interprets as sound.

⭐A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium

✨Medium such as
➡ air,
➡water
➡any other liquid
➡ solid matter.

$\huge{HELLO, FRIEND}$

$<b>HERE IS YOUR ANSWER ⤵️⤵️⤵️$
YOU CAN GO THROUGH IT ^_^
☺️♥️☺️

$\huge{SOUND}$ is a form of energy. Sound is that form of energy which makes us here. Each sound has special objects which produce it. Sound is produced by vibrating objects. Sound always needs a medium to travel. Sound travels more faster in solid as compared to medium like air. FOR EG: If you keep your ear on the railway track you can hear the sound of the coming train even if it is too far away from you. BUT, we will not hear the sound of coming train from the medium air if the train is too far from us. It is a proof that sound travels faster in solid.
