Consider two pipes of identical length: one open at one end and one open at both ends. Select the correct statement below that describes the fundamental frequency of a sound wave in air in each pipe. ☐ a. The value of the fundamental frequency is the same for both pipes. Ob. The value of the fundamental frequency is lower for the open pipe. О с. The value of the fundamental frequency is lower for the pipe closed at one end.

.Negative decibels? Our discussion of decibels did not mention that they can be negative. On the Redmond, Washington campus of Microsoft is an anechoic chamber that, according to Guinness World Records, is the quietest place in the world. It measures –20.3 decibels. a. What is the relative intensity of a sound measuring –1 decibels? Round your answer to one decimal place. b. What is the relative intensity of a sound measuring –10 decibels? Round your answer to one decimal place. c. What is the relative intensity of Microsoft's anechoic chamber? Round your answer to three decimal places. d. Is it possible for the relative intensity to actually be zero?

A.) I have an open-closed tube with a length of 0.7 m and a radius of 0.5 cm. What is the wavelength of mode number 2, in m? B.) I have an open-open tube with a length of 0.7 m and a radius of 1.6 cm. What is the frequency of mode number 1, in Hz? The speed of sound is 343 m/

The first harmonic of a series created by a standing air wave in a tube open at one end only is 36.9 Hz. If the length of the tube is 235 cm, calculate the speed of sound of the air. Use two digits of precision for your answer. Your Answer: + Answer

Select the correct expressions for the first three overtones of an open pipe with the fundamental frequency fo . Select one or more: O a. f2 = 3 fo O b. f3 = 4fo O c. f1 = 2 fo O d. f2 = fo O e. f3 = fo O f. f3 = fo 5

Consider the sound created by resonating the tube shown below. The air temperature is TC = 30.00°C . What are the wavelength, wave speed, and frequency of the sound produced?
