Identical cellos are being tested. One is producing a fundamental frequency of 128.9 Hz on a string that is 1.40 m long and has a mass of 109 g. On the second cello an identical string is fingered to reduce the length that can vibrate.

If the beat frequency produced by these two strings is 3.25 Hz , what is the vibrating length of the second string?

    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,...

    The G string on a violin has a fundamental frequency of 196 Hz. It is 31.0 cm long and has a mass of 0.500 g. While this string is sounding, a nearby violinist effectively shortens the G string on her identical violin (by sliding her finger down the sting) until a beat frequency of 4.00 Hz is heard between the two strings. When that occurs, what is the effective length of her string? ___cm (please write solution legibly)

    A pipe open only at one end has a fundamental frequency of 254 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now when both pipes vibrate at their fundamental frequencies, a beat frequency of 20 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 345 m/s.

    A pipe open only at one end has a fundamental frequency of 240 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now when both pipes vibrate at their fundamental frequencies, a beat frequency of 16 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 345 m/s.

    A pipe open only at one end has a fundamental frequency of 240 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now when both pipes vibrate at their fundamental frequencies, a beat frequency of 12 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 348 m/s.

    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...

    A cellist tunes the C-string of her instrument to a fundamental frequency of 65.4 Hz . The vibrating portion of the string is 0.600 m long and has a mass of 14.7 g . What percentage increase in tension is needed to increase the frequency from 65.4 Hz to 73.4 Hz , corresponding to a rise in pitch from C to D?

    The G string on a violin has a fundamental frequency of 196 Hz. It is 30.0 cm long. While this string is sounding, a nearby violinist effectively shortens (by sliding her finger down the string) the G string on her violin until a beat frequency of 4.7 Hz is heard between the strings on the two violins. When this occurs, how far (cm) down the string did she slide her finger? Assume that the velocity of waves on the violin...

    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...
