The following two lists give the diameters and sound frequencies for three loudspeakers. Pair each diameter with a frequency, so that the diffraction angle is the same for each of the speakers, and then find the common diffraction angle. Take the speed of sound to be 343 m/s. Diameter, D Frequency, f 0.050 m.........................6.0 kHz 0.10 m...........................4.0 kHz 0.15 m.........................12.0 kHz
