The document covers class 12 physics notes on sound waves containing top concepts like wave motion, mechanical wave motion, progressive wave, superposition principle, stationary waves etc. Espinoza also relies on students own experience to guide their learning. In the case of sound waves, the vibrations create a series of compressions and expansions and the wave travels along the compression in the direction of the propagation. As we lower the temperature so the motion of the particles is reduced until a point is reached. Since the particles are moving in parallel direction to the wave movement, the sound wave is referred to as a longitudinal wave. In a longitudinal wave, the vibration of the particles of the medium is along the direction of the waves motion.
