7. A guitar string is 1 m long and has a mass of 4.5 g. The distance from the bridge to the support post is e = 62 cm, and the string is under a tension of 650 N. What are the frequencies of the %3! fundamental and first overtones?

A harpsichord string of length 1.50 m and linear mass density 25.0 mg/m vibrates at a fundamental frequency of 447.0 Hz. A) What is the speed of the transverse string waves? in m/s B) What is the tension? in N  C) What is the wavelength of the sound wave in air produced by the vibration of the string? (The speed of sound in air at room temperature is 343 m/s.) in m D)  What is the frequency of the sound wave in air produced by the vibration of the string? (The speed of sound in air at room temperature is 343 m/s. in Hz

A standing wave in a guitar string has 4 nodes and a wavelength of 1 m. What is the position xx of the n=1 node?

What is the frequency of the fundamental? What is the wave speed?

2. Emma needs to know the fundamental frequency of a guitar string. She sounds the string together with an 840Hz tuning fork, and counts 15 beats in 5.0s. She then sounds the string with an 835Hz tuning fork and counts 2 beats every second. What is the frequency of the string?

Shi 48. A guitar has 4 strings. The mass per unit length of the G string is 4 times the mass per unit length of the E string. If they are both connected to the guitar and tightened to a tension of 100 N how does the fundamental wavelength of the E string compare to the fundamental wavelength of the G string? O A.
