Sound: Compressions and Rarefactions: a 3D model for Class 9 Science, covering Sound is a disturbance that travels through a medium such as air; the medium is needed…, A vibrating object pushes the air next to it, making a compression (high pressure and density), then pulls back…, Sound is a longitudinal wave: the particles of the medium vibrate back and forth along the same line the wave travels., The particles are not carried along by the wave; each one returns to its resting position after every full vibration., Wavelength is the distance between two neighbouring compressions (or two neighbouring rarefactions)..
