Concept explainers

A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).

Quality Of Sound

A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vib…

Categories of Sound Wave

People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules th…

Textbook Question

Chapter 11, Problem 62P

* A 1.2-m-long open-closed pipe is producing sound by vibrating with its third harmonic. (a) Determine the frequency of the sound. (b) How long should a pipe of the same type be to produce sound of the same frequency while at the fundamental frequency? (c) How would the answers to parts (a) and (b) change if the pipe was filled with helium, in which the speed of sound is about three times larger than in air? Explain.

Compare the slope of your Data Table 2 graph to the average wavelength (Ave, l) from Data Table 2 by calculating the % Difference. Is the % Difference calculated for the wavelength in Data Table 2 within an acceptable % error? Explain why or why not?

The slope of a graph of velocity, v, vs frequency, f, is equal to wavelength, l. Compare the slope of your Data Table 1 graph to the average wavelength (Ave, l) from Data Table 1 by calculating the % Difference.

Examine the slope of the line on the graph created using the data in Data Table 4 of Period, T2 vs L, the slope of the line is a constant containing the acceleration due to gravity, g. Using the slope of your line, determine the experimental value for g. Compare the value you determined for g from the slope of the graph to the expected value of 9.81 m/s2 by calculating the percent error.
