Explain why strings of different thickness are provided on stringed instrument.
[Hint — Natural frequency of vibration of a stretched string is inversely proportional to the radius (or thickness) of string so notes of different frequencies can be obtained by producing vibrations in the different strings]

Answer
As we know,
frequency (f) =
So, we can say that the natural frequency of vibration of a stretched string is inversely proportional to the radius of the string.
Hence, in order to produce sound waves of different frequencies, strings of different thickness are provided on a stringed instrument.
