A tuning fork that vibrates at a frequency 680 Hz is placed over an 80 centimeter long cylinder that is completely filled with water. The water is then allowed to drain out, creating an air column of varying length above the surface of the water and inside the cylinder. Find the distances d between the top of the cylinder and the surface of the water for which the air column will resonate at 680 Hz. Assume that the speed of sound is 340 m/s.

A well with vertical sides and water at the bottom resonates at 7.00 Hz and at no lower frequency. (The air filled portion of the well acts as a tube with one closed end and one open end.) The air in the well has a density of 1.10 kg/m^3 and a bulk modulus of 1.33×10^5 Pa. How far down in the well is the water surface?

A flute may be thought of as a pipe open at both ends. When all the holes of a well-designed flute are covered and the temperature is 20.0°C, it will produce sound with a frequency of 261.6 Hz (middle C). The speed of sound in air at 20.0°C is 343 m/s. (a) Find the length of the flute (in m), assuming middle C is the fundamental. 0.655 m (b) When an identical flute is played at the same time and in the same manner (all holes covered) in a nearby cold room, the cold room (in °C). beat frequency of 1.60 Hz is heard. Determine the temperature in x First, establish if the frequency in the cold room will be greater or smaller than in the warm room. See if you can write an expression which shows how the frequency depends on speed of sound and the length of the flute for both the warm and cold room and then combine these expressions to obtain the speed of sound in the cold room. Knowing the speed of sound in the cold room and how the speed of sound depends on the temperature, you can now…

A tuning fork is held over the top of a graduated cylinder that is slowly filled with water. Two resonances are noted as the cylinder is filled. They occur when the water level is 56.5 cm and 17.5 cm below the rim. Note that there is an end correction, meaning that the effective length of the air column is longer than the observed length by a fixed constant amount. If the speed of sound is 343 m/s, find the frequency of the tuning fork.

A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (a) What is the speed of sound in the flute? A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (b) What is the wavelength of the first harmonic? Consider the flute to be a pipe open at both ends  A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (c)Consider the flute to be a pipe open at both ends and find its length, assuming this frequency is the fundamental frequency A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. A second player, nearby in a colder room, also attempts to play middle C on an identical flute. A beat frequency of 3.00 beats/s is heard.  (e) What is the speed of sound in the second room? A flute is designed so that it plays a…

A train is moving away from an observer at a speed of 50 m/s with its whistle on, the frequency of the whistling sound being 400 Hz. What should be the approximate frequency heard by a stationary observer? Take the speed of sound as 345 m/s when atmospheric temperature is 24°C. 328 Hz 310 Hz 380 Hz 349 Hz

If Mel’s face is 38.9 cm in front of a concave shaving mirror creating an upright image 1.46 times as large as the object, what is the mirror’s focal length?  To continue please enter the result in units of cm.   Round your answer to 1 decimal place.

If the vocal tract of a human is considered a closed tube 17 cm in length, what is the frequency of what would become the second harmonic? Consider 340 m/s as the speed of sound. The answer must be in Hz units.

Deep ultrasonic heating is used to promote healing of torn tendons. It is produced by applying ultrasonic sound over the affected area of the body. The sound transducer (generator) is circular with a radius of 1.46 cm, and it produces a sound intensity of 6.53 × 103 W/m2. How much time is required for the transducer to emit 3910 J of sound energy?

The speed of sound in a solid medium is given by ?=?/?‾‾‾‾√v=E/ρ where ?E is the value of Young's modulus for the solid and ?ρ is the density.  A sound wave travels at 5.8×1035.8×103 m/s in a steel rod of length 1.11 m, diameter 2.0 cm and mass 7.0 kg.  Use the data to determine the value of the Young's modulus for steel. Give your answer in giga-pascal (GPa, 109 Nm-2).
