Question 3 The cords of a musical instrument are fixed at both ends, find the nth...
A string fixed at both ends has successive resonances with wavelengths of 0.55 m for the nth harmonic and 0.53 m for the (n + 1)th harmonic. (a) What are the following values? nth harmonic (n + 1)th harmonic (b) What is the length of the string? m Use the fact that the resonance frequencies are multiples of the fundamental frequency and are expressible in terms of the speed of the waves and their wavelengths to find the harmonic numbers....
A string is stretched to a length of 406 cm and both ends are fixed. If the density of the string is 0.0066 g/cm, and it’s tension is 924 N, what is the fundamental frequency? Answer in units of Hz.
a string is fixed at both ends and is vibrating at 130 Hz l, which is its third harmonic frequency. the linear density of the string is 5.6 x 10^-3 kg/m, and it is under a tension of 3.3 N. determine the length of the string.
Consider a musical instrument that can be regarded as a long pipe with both ends closed (see Fig. 1). Let the pipe length L=0.250 m. Closed ends mean that you should have nodes at the two ends. Assume sound speed to be v=330 m/s. (6 points) Consider a musical instrument that can be regarded as a long pipe with both ends closed (see Fig. 1). Let the pipe length L 0.250 m. Closed ends mean that you should have nodes...
A string is stretched and fixed at both ends, 300 cm apart. if the density of the string is 0.025 g/cm, and its tension is 800 N, what is the frequency of the 2nd harmonic?
A guitar string of length 80 cm is fixed at both ends. The string has a uniform volume density of 9000 kg/m and has a diameter of 0.75 mm. The string is under a tension of 40 N. Determine the wavelength of the fundamental harmonic on the guitar string. Calculate the wavelength of the sound wave traveling through air emitted by the first guitar string if the string is oscillating in the fundamental harmonic.
For a stringed instrument, the tension on each string must be roughly the same to avoid warping. Suppose each string on an acoustic guitar has a tension of 79 N and is 64 cm long. The steel core of the string has a density of 7970 kg/m3. If the wavelength on a string is twice its length, then what is the linear density for the low E string (f = 82.4 Hz)? Answer=7.10e-03 kg/m What is the string's diameter? Traditionally,...
need help with solving question 1 and 2 1. A string is tied at both ends. It has a linear mass density of 5 (grams/cm) and a tension of 8 (N). What is the velocity of the wave? 2. In the above question, if the frequency of the wave is 100 (Hz), what is the shortest length of the string?
3. A string fixed at both ends is 8.8 m long and has a mass of 0.14 kg. It is subjected to a tension of 97 N and set oscilating. (a) What is the longest possible wavelength for a standing wave? (b) Give the frequency if the string produces 5 nodes.
A thin 3-m string of mass 50.0 g is fixed at both ends and under a tension of 81 N. If it is set into small-amplitude oscillation, what is the frequency of the first harmonic mode?
