Loudness of sound Human ear is natural sound receiver. Sound originates from the source as waves and propagates through the medium and produces vibration in…

Bel: The amount of increase in loudness of a sound when its intensity increases ten times is called 1 bel. It is a unit used…

Resonance Explanation with Characteristics When the natural frequency of a body becomes equal to the frequency of forced vibration, then the body vibrates with maximum…

Resonance When a vibrating body is held near another body, then the second body starts vibrating. It is called forced vibration. If the natural time…

Name of the experiment: Melde’s Experiment Theory: One end of a thread is fastened to one end of a tuning fork passed the thread through…

Condition for propagation of Stationary Waves Stationary waves can form under a variety of conditions, but they are easily demonstrated in a medium which is…

Experiment for the production of stationary wave: Attach a scale pan at one end of a string taken over a pulley. Attach the other end…

Characteristics of stationary wave: The resultant wave produced by the superposition of two progressive waves having the same wavelength and amplitude, travelling in opposite direction…

The stationary wave can be produced for both transverse and longitudinal waves. If two ends of a string are fastened straight and if, at a…

Principle of Superposition Law: – When two or more waves pass simultaneously through the same medium, the resultant displacement of each particle of the medium…
