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

A musician in a concert hall is tuning her wind instrument. When she plays a short note she hears the echo of the note return from the opposite side of the 50.0 meter long auditorium 0.294 seconds later. Model the instrument as a tube closed at one end, if the instrument is properly tuned the note of the musician played would have a frequency of 233.082 Hz, but instead has a frequency of 226.513 Hz. This note is the first...
