Waves and Sound

Characteristics of beats: When two sound waves of equal or nearly equal intensity and nearly equal frequencies originate at the same time and travel along…

Conditions for the formation of beats The wave’s amplitude and the frequency of beating should be similar; it just depends on column/height that is large…

Beats Experiment Take two tuning forks of same frequencies and place them vertically on a hollow box. Now strike one of the two forks on…

Intensity Level of Sound The loudness of a sound is the magnitude of the auditory sensation produced by the sound. It depends upon both intensity…

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…
