- Two pianos each sound the same note simultaneously, but they are both out of tune. On a day when the speed of sound is 341 m/s, piano A produces a wavelength of 0.763 m, while piano B produces a wavelength of 0.780 m. How much time separates successive beats?On a guitar, the lowest-toned string is usually strung to the E note, which produces sound at 82.4 Hz. The diameter of E guitar strings is typically 0.0500 in, and the scale length between the bridge and nut (the effective length of the string) is 25.5 in. Various musical acts tune their E strings down to produce a "heavier" sound or to better fit the vocal range of the singer. As a guitarist you want to detune the E on your guitar to D (73.4 Hz). If you were to maintain the same tension in the string as with the E string, what diameter d det of string would you need to purchase to produce the desired note? Assume all strings available to you are made of the same material. d det = inches %3D Unfortunately, none of the strings in your collection have such a large diameter. In fact, the largest diameter you possess is 0.05307 in. If the tension on your existing string is denoted Tbefore, by what fraction will you need to detune (that is, lower the tension) of this string to achieve the…Two identical guitar strings are prepared such that they have the same length (0.68) and are under the same amount of tension. The first string is plucked at one location, primarily exciting the first harmonic. The other string is plucked in a different location, primarily exciting the fourth harmonic. The resulting sounds give rise to a beat frequency of 324Hz. What is the wave propagation speed on the guitar strings? wave propagation speed: m/s

What is the tension needed to produce the E note?A guitar string has an overall length of 2.0 m and a total mass of 35.2 g before it is strung on a guitar. Once on the guitar, however, there is a distance of 85 cm between its fixed end points. It is tightened to a tension of 345 N. (a) What is wave speed for waves on the tightened string? (b) What are the wavelength and frequency of the traveling waves that interfere to form the fundamental and second harmonic standing waves on the string?

- The ear canal can be thought of as a tube leading from the outer ear to the ear drum that is closed at one end. The typical length of an adult human ear canal is 2.5 cm. What is the fundamental resonant frequency of the ear canal? Assume the air inside it is at body temperature (37°C).A train's whistle produces a sound known to have a frequency of exactly 500 Hz. Standing still with a radar gun directly in the path of an oncoming train moving toward you, you measure its speed to be 24.8 m/s. Your keen ear perceives a frequency of 538.5 Hz regarding its blowing whistle as it steams towards you. Being the scientist that you are, you proceed to step off of the tracks and use your data to determine the air temperature outside. Measured in degrees Celsius, what do you conclude it to be?
