What is the evidence that sound is a form of energy?
Following are the point which shows that sound is in the form of energy.
Consider the following characteristics of energy:
The following points can be observed for sound relative to energy:
Thus, the sound is a form of energy.
(II) The two sources of sound in Fig. 12–16 face each other and emit sounds of equal amplitude and equal frequency (305 Hz) but 180° out of phase. For what minimum separation of the two speakers will there be some point at which (a) complete constructive interference occurs and (b) complete destructive interference occurs. (Assume T = 20°C.)
Question: Manufacturers typically offer a particular guitar string in a choice of diameters so that players can tune their instruments with a preferred string tension. For example, a nylon high-E string is available in a low- and high-tension model with diameter 0.699 mm and 0.724 mm, respectively. Assuming the density \(\rho \) of nylon is the same for each model, compare (as a ratio) the tension in a tuned high-and-low tension string.
