A free-standing guitar string is 0.68m long and is tuned to play
an E (330Hz).
a) How far from the end of the string should you put your finger to
play an A (440Hz)?
b) A pipe that has one end closed and the other end open also wants
to play an A using the overtone that is two higher than the
fundamental. What is the length of the pipe?
I need help on Part B. We aren't given the speed of air or sound so we have to be able to solve it without those values.

The D-string on a properly tuned guitar produces a tone with a fundamental frequency of 146.8 Hz. The oscillating length of a D-string on a certain guitar is 0.65 m. This same length of string is weighed and found have a mass of 1.4×10-3 kg. 25% Part (a) At what tension, in newtons, must the D-string must be stretched in order for it to be properly tuned? T = 78.443 T = 78.44 ✔ Correct! 25% Part (b) What is the...
One of the 57.5cm -long strings of an ordinary guitar is tuned to produce the note B3(frequency 245 Hz) when vibrating in its fundamental mode. 1. Find the speed of transverse waves on this string. 2. If the speed of sound in the surrounding air is 344 m/s, find the frequency of the sound wave produced in the air by the vibration of the B3 string. 3. If the speed of sound in the surrounding air is 344 m/s, find...
part 1. A 9.00-m long string sustains a three-loop standing wave pattern as shown. The string has a mass of 45 g and under a tension of 50 N. a. What is the frequency of vibration? b. At the same frequency, you wish to see four loops, what tension you need to use. Part 2. a. Determine the shortest length of pipe, open at both ends, which will resonate at 256 Hz (so the first harmonics is 256Hz). The speed...
Standing sound waves are produced in a pipe that is 1.20 m long. a)If the pipe is closed at the left end and open at the right end, determine the locations along the pipe (measured from the left end) of the displacement nodes for the first overtone. Express your answer(s) in meters to three significant figures, separated by commas, if there is more than one location. b)If the pipe is closed at the left end and open at the right...
The A string of a violin is 34 cm long between fixed points with a fundamental frequency of 440 Hz and a mass per unit length of 6.2×10−4 kg/m . What is the wave speed in the string? What is the tension in the string? What is the length of the tube of a simple wind instrument (say, an organ pipe) closed at one end whose fundamental is also 440 Hz if the speed of sound is 343m/s in air?...
The lowest string of a certain guitar is 64 cm long and has a mass density of 6.3 g/m. The string is fixed at its ends by the bridge and the nut of the guitar. (a) What tension in the string is required to tune it so that its fundamental frequency matches the E2 musical note at 82.41 Hz? Give an answer in both N and lbs. (b) The effective string length can be shortened by pressing your finger down...
Questions: 1. Explain how you can raise the pitch of a note on a guitar by altering the string’s (a) length, (b) tension, or (c) thickness or mass. Be very specific about what you would do to raise the pitch. 2. If the fundamental frequency of a guitar string is 250 Hz, what is the frequency of the second harmonic? Of the third harmonic? Explain. 3. Consider a vibrating guitar string. The loudest harmonic is the fundamental, but many higher...
What is the lowest frequency (excluding the fundamental) at which standing wave can occur in a 0.85-m long pipe with one end open and one end closed. The speed of sound in air is 337 m/s.
what is the lowest frequency (excluding the fundamental) at which standing wave can occur in a 0.85-m long pipe with one end open and one end closed. The speed of sound in air is 335 m/s.
Question 4 1 pts You play a low G note on a guitar and the string vibrates about 100 times every second. If your friend sings a G note that is 2 octaves higher than this, how many times per second will her vocal cords vibrate? (In both cases we are referring to the frequency of the fundamental) 25 50 100 200 300 400 Question 3 1 pts Your speaker level is set to 50 decibels. You turn it up...
