The string of a violing emits a note of 440Hz at its correct tension. The string is bit taut and produces 4 beats per sec with a tuning fork of freq. 440Hz. Find the frequency of the note emitted by this taut string.

Text Solution

Verified by Experts

As, `nprop sqrt(T)`, therefore, freq. of vibration of string increases. As it gives 4 best `//` sec with a fork of frequency 440, therefore, its frequency would be `440+4=444Hz`.
