(a) When sound emerges from a loudspeaker, is the diffraction angle determined by the wavelength, the diameter of the speaker, or a combination of these two factors?
(b) How is the wavelength of a sound related to its frequency ? Explain your answers.
The following two lists give diameters and sound frequencies for three loudspeakers. Par each diameter with a frequency, so that the diffraction angle is the same for each of the speakers. The speed of sound is 343 m/s. Find the common diffraction angle.
Diameter, D .050m .10m .15m
Frequency, f 6.0 kHz 4.0 kHz 12.0 kHz
The solution carefully explains the problem and the answer with narrative and calculations.
