Waves and Sound

Superposition of waves: The principle of superposition may be applied to waves whenever two (or more) waves travelling through the same medium at the similar…

Noise and Musical Sound and their Effect We hear different sounds around us. For examples, the pattering sound of rainfall, tone of violin, note of…

Meaningful sounds that we hear originate due to the combination of many frequencies. If these frequencies are mutually simple multiple, then resultant sound produced by…

Musical Interval or Musical Proportion Most of the meaningful words which we hear are composed of different frequencies. This frequency, being the simple multiple of…

The contribution of Physics in the Analysis of Musical Sound We know the characteristics by which we can distinguish clearly two sounds having same loudness…

Harmonics We know, different tones exist in a music. The tone having lowest frequency in them is called fundamental tone. Other tones whose frequencies are…

Musical Scale We know in a tone there exists low and high frequencies. A tone of lowest frequency is called key note. Values of tones…

Mathematical Expression of Beat Let consider two sounded tuning forks having frequencies n1 and n2 (n1> n2) and the difference between the two frequencies is…

Application of Beats When two sound waves of equal or nearly equal intensity and nearly equal frequencies originate at the same time and travel along…

Mechanism of Formation of Beats When two sound waves of nearly equal frequencies originate at the same time and travel along the same direction, meet…
