The A string of a violin is a little too tightly stretched. Beats at 4 per second are heard when the string is sounded together with a tuning fork that is oscillating accurately at concert A (440 Hz). What is the period of the violin string oscillation?
Homework Answers
1/444 second.
With 4 beats/sec,
the violin string and the tuning fork are in phase 4 times per sec.
This happens when the frequencies differ by 4 Hz.
Since it's too taut, it's vibrating at a frequency above 440 Hz,
thus at 444 Hz.
Period = 1/frequency = 1/444 sec.

A violinist tuning a string on her instrument to a tuning fork of 440 Hz detects 4 beats per second. When she loosens the string (which de- creases the frequency of the sound produced by the string), the number of beats per second initially goes down, but as she continues to loosen the string, the number of beats per second starts to increase. The fre- quency of the sound produced by the string on her violin before she started loosening...

Question 5 1 pts Tuning fork A has a frequency of 440 Hz. When A and a second tuning fork B are struck simultaneously, four beats per second are heard. When a small mass is added to one of the tines of B, the two forks struck simultaneously produce two beats per second. The original frequency of tuning fork B was 436 Hz. 432 Hz. 444 Hz. 448 Hz 438 Hz.

What is the relationship between wave frequency and period? If the frequency of a wave doubles, what happens to its period? If the period doubles, what happens to the frequency?What are beats? How are beats related to frequency? A piano tuner hears three beats per second when a tuning fork and a note are sounded together and six beats per second after the string is tightened. What should the tuner do next, tighten or loosen the string? Explain your answer.What...

A flutist assembles her flute in a room where the speed of sound is 342 m/s . When she plays the note A, it is in perfect tune with a 440 Hz tuning fork. After a few minutes, the air inside her flute has warmed to where the speed of sound is 343 m/s. How many beats per second will she hear if she now plays the note A as the tuning fork is sounded? How far does she need...
