In nearly all areas of science and therefore real life energy is transferred via the vibrations that make up waves. We have listed top multiple choice questions and answers on sound wave in physics. Wave motion is classified into three different ways they are, the medium of propagation, the dimensions in which a wave propagates energy, the energy transfer. Even more important, though only touched on in this book, is the wave phenomenon of quantum mechanics, built into the fabric of our space and time. We will start with periodic motion for the rst two lectures, with our speci c examples being the motion of a mass attached to the end of a spring, and the pendulum. Introduction and types a wave is a transfer of energy through a medium from one point to another.

Sound natural frequency frequency at which an elastic object naturally tends to vibrate, so that minimum energy is required to produce a forced vibration or to continue vibration at that frequency. The toandfro vibratory motion is often called oscillatory motion. The form of the dependence of the traveling wave parameters upon each other is a consequence of the basic motion equation and the definitions of the the terms which describe periodic motion.
