AP PSYCHOLOGY

Detailed explanation-1: -Sound wave consists of vibrating particles. These knock into other particles causing them to vibrate, and so the sound can travel away from the source. You can hear sound because the vibrations in the air cause your ear drums to vibrate. This vibration is converted into signals which travel down a nerve to your brain.

Detailed explanation-2: -For a vibration to occur an object must repeat a movement during a time interval. A wave is a disturbance that extends from one place to another through space. Light and sound are vibrations that move through space–they are waves! A pendulum swings in a periodic motion.

Detailed explanation-3: -Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.

Detailed explanation-4: -Let us understand the concept of sound produced by the vibration of an object with an example. We might have seen people playing the guitar. In guitar when they pluck the strings of a guitar, it vibrates and produces sound. The sound produced by it travels through the air which acts as the medium.
