NOTES Chapter 12: "Sound" from Class 9 Science CBSE NCERT:

  summary of Chapter 12: "Sound" from Class 9 Science CBSE NCERT : 1. What is Sound? Sound is a form of energy that is produced by the vibration of objects and propagates through a medium (solid, liquid, or gas) in the form of waves. Sound travels in waves and can be heard when it reaches our ears . How is sound produced? Sound is produced when an object vibrates. These vibrations cause the particles of the medium to move, creating compressions and rarefactions (regions of high and low pressure) that travel through the medium. 2. Propagation of Sound Sound needs a medium (like air, water, or solid objects) to travel. It cannot travel in a vacuum. How sound waves travel : Sound waves are longitudinal waves (particles of the medium move in the same direction as the wave). When an object vibrates, it creates a series of compressions (regions where particles are close together) and rarefactions (regions where particles are spread apart) in the surrounding medium. These co...
