Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...

A piano tuner sounds two strings simultaneously. One has been previously tuned to vibrate at 293.0 ??. The tuner hears 3.0 beats per second. The tuner increases the tension on the as-yet untuned string, and now when they are played together the beat frequency is 1.0 beat per second. (a) What was the original frequency of the untuned string? (b) What is the frequency of the unturned string corresponding to 1.0 beat per second? (c) By what percentage did the...

Identical cellos are being tested. One is producing a fundamental frequency of 248 Hz on a string that is 1.06 m long and has a mass of 100.0 g. On the second cello the same string is fingered to reduce the length that can vibrate. If the beat frequency produced by these two strings is 4.0 Hz, what is the vibrating length of the second string? (Express your answer to the nearest hundredth of a meter.) _____m I got 1.13m,...

A simple instrument consists of two metal strings stretched parallel to one another and attached at both ends to boards perpendicular to the strings. The tension is the same in both strings, and the length of the strings is ` = 35.0 cm. The first string has a mass m = 8.00 g and generates middle C (frequency f = 262 Hz) when vibrating in its fundamental mode. a) What is the tension in the first string? b) If the...
