प्रश्न
Explain why (or how) A violin note and sitar note may have the same frequency, yet we can distinguish between the two notes,
Advertisements
उत्तर १
The overtones produced by a sitar and a violin, and the strengths of these overtones, are different. Hence, one can distinguish between the notes produced by a sitar and a violin even if they have the same frequency of vibration.
उत्तर २
The quality of a violin note is different from the quality of sitar. Therefore, they emit different harmonics which can be observed by human ear and used to differentiate between the two notes.
