Sound Wave and basic Oscillations
What you'll learn
The simple harmonic oscillation is a simplest periodic motion of particle or system which occurs only under linear restoring force. It is ideal periodic motion
The periodic motion of the particle or system under linear restoring force and medium damping is called under damped harmonic oscillation for small damping.
For forced oscillation of the particle, external periodic driving force is applied to the particle along with the restoring force and damping force by medium
For under damped harmonic oscillation, the damping effect in presence of the medium will be small. Otherwise for large damping, the motion will be over damped.
Requirements
The knowledge about oscillation of the particle or system will be developed at basic as well as at advance level. Moreover the basic knowledge about Sound wave will be also achieved from this course
Description
The oscillation is basically a periodic motion which may occur in several conditions and thus there are several type of oscillation. This oscillation or periodic motion can be classified into four classes which are Simple Harmonic Motion, Damped Harmonic Oscillation, Forced Oscillation and Coupled Oscillation. For SHM or Simple Harmonic Oscillation, only restoring force will be effective on the oscillating particle and it is an ideal oscillation which can not be obtained in reality. When medium damping will be present along with the restoring force then it is called Damped motion and for small damping it is called Under Damped Harmonic Oscillation. Otherwise for comparatively large damping factor as offered by the medium, it will be either Critically Damped or Over Damped Oscillation without Oscillation. For forced oscillation, the major periodic force will be applied on the oscillating particle in presence of restoring force and damping force. In case of forced oscillation which will be totally controlled by the external driven force, resonance occurs when the natural frequency of oscillation will be equal to the frequency of the external driving force. This resonance is essentially power resonance where we can measure the band width from the corresponding Response curve. The Band Width BW is significant for Quality factor and sharpness of resonance. In this content we also discuss the production and several features of Sound wave which is very common type of Longitudinal elastic wave. Here the features of sound wave which are discussed here are its phase velocity and its parameter dependence, Energy transmission, Intensity and Intensity Level along with the loudness of the elastic sound wave .. etc. All such discussions of this content are very useful for students for their preparation at several levels.
The both slow and advance learners will be mostly benefited from this course
