Chapter 17: Q.33 (page 484)

A flute player hears four beats per second when she compares her note to a 523 Hz tuning fork (the note C). She can match the frequency of the tuning fork by pulling out the 鈥渢uning joint鈥� to lengthen her flute slightly. What was her initial frequency?

Short Answer

Expert verified

The initial frequency of the flute player is 519Hz

Step by step solution

01

Write the given information

Frequency of the fork f1 = 523 Hz

Beat frequency fb= 4 Hz

02

To determine the initial frequency

Let the initial frequency of the string is f2

According to the question
f1-f2=fbf2=(523-4)Hzf2=519Hz

Thus, the initial frequency of the flute player is 519Hz

Deep-sea divers often breathe a mixture of helium and oxygen to avoid getting the 鈥渂ends鈥� from breathing high-pressure nitrogen. The helium has the side effect of making the divers鈥� voices sound odd. Although your vocal tract can be roughly described as an open-closed tube, the way you hold your mouth and position your lips greatly affects the standing-wave frequencies of the vocal tract. This is what allows different vowels to sound different. The 鈥渆e鈥� sound is made by shaping your vocal tract to have standing- wave frequencies at, normally, 270 Hz and 2300 Hz. What will these frequencies be for a helium-oxygen mixture in which the speed of sound at body temperature is 750 m/s? The speed of sound in air at body temperature is 350 m/s.

A sheet of glass is coated with a 500-nm-thick layer of oil 1n = 1.422.

a. For what visible wavelengths of light do the reflected waves interfere constructively?

b. For what visible wavelengths of light do the reflected waves interfere destructively?

c. What is the color of reflected light? What is the color of transmitted light?

FIGURE EX17.6 shows a standing wave on a 2.0-m-long string that has been fixed at both ends and tightened until the wave speed is 40 m/s. What is the frequency?

Tendons are, essentially, elastic cords stretched between two fixed ends. As such, they can support standing waves. A woman has a 20-cm-long Achilles tendon鈥攃onnecting the heel to a muscle in the calf鈥攚ith a cross-section area of 90 mm2.. The density of tendon tissue is 1100 kg/m3. For a reasonable tension of 500 N, what will be the fundamental frequency of her Achilles tendon?

What are the three longest wavelengths for standing sound waves in a 121-cm-long tube that is (a) open at both ends and (b) open at one end, closed at the other?
