Sound Chapter Class 9 Notes
Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid, or solid.
Sound is a pressure wave which is created by a vibrating object. This vibration sets particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.
Sound travels from one path to another. The sound compression regions of higher density. Sound is a pressure wave which is created by a vibrating object.
This vibration sets particles in the surrounding medium (typical air) in vibrational motion, thus transporting energy through the medium.
