A violinist is tuning her instrument to concert A (440 Hz ). She plays the note while listening to an electronically generated tone of exactly that frequency and hears a beat of frequency 5.00 Hz , which increases to 6.00 Hz when she tightens her violin string slightly. What was the frequency of her violin when she heard the 5.00 Hz beat?

Solutions

Expert Solution

since on tightening the string tension increases therefore frequency increases

as the beat frequency is increased on tightening the string

the frequency of instrument is high

5 = f -440

f = 445Hz
