为什么声音需要介质传播？
1、声音是由物体的振动产生的，这些振动需要通过介质（如空气、水或固体）来传递能量。
2、在真空中，没有介质分子来传递振动，因此声音无法传播，这也是为什么宇航员在太空中需要通过无线电通讯的原因。
3、不同介质的密度和弹性不同，会影响声音传播的速度和效果。例如，声音在固体中传播得更快，因为固体分子更紧密。
4、声音的传播是通过介质中的分子相互碰撞来实现的，这种碰撞会传递能量，从而让声音传播到远处。
5、介质的选择也会影响声音的清晰度和音质。例如，在空气中传播的声音会因距离和障碍物而衰减，而在水中传播的声音则更清晰。
总之，声音需要介质传播是因为振动需要通过介质中的分子来传递能量，没有介质，振动无法传播，声音也就无法听到。
