A sound wave a frequency of 20 kHz emerges through a circular opening that has a diameter of 0.78 m. Concepts: The diffraction angle for a wave emerging through a circular opening is given by sin(theta) = 1.22 /D, where is the wavelength of the sound and D is the diameter of the opening. What is meant by the diffraction angle? the angle that the sound wave bends away from the center before passing through the opening the location of...
