Please show all your work. A source of sound is located in a room a distance “L” from a wall. The room temperature is 72°F. AN observer is located between the source and the wall at 103 cm from the wall. The observer can hear a loud sound at the 3rd harmonic and the sound fades at the 4th harmonic. What is the velocity of sound in the room? What is the frequency at which the observer can hear the...

A flutist assembles her flute in a room where the speed of sound is 342 m/s . When she plays the note A, it is in perfect tune with a 440 Hz tuning fork. After a few minutes, the air inside her flute has warmed to where the speed of sound is 343 m/s . You may assume in this problem that the construction of a flute makes it behave like a pipe which is open on both ends. How...

a) A 1 meter long guitar string of linear mass density 2g/m3 is put under tension until it resonates with a fundamental frequency of 440 Hz. Determine the tension that produces this fundamental frequency. Also determine the other of the first four harmonic frequencies and draw diagrams illustrating what each of these oscillations looks like on the string. b) This string will produce sound waves in the air, determine the wavelength of the sound waves. c) Suppose you had two...
