A sound wave with a frequency of 20 kHz emerges through a circular opening that has a diameter of 0.28 m. Concepts: (i) The diffraction angle for a wave emerging through a circular opening is given by sin(0) = 1.22 /D, where A 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 toward the center before passing through the opening the location of the first minimum intensity point on either side of the center the location of the first maximum intensity point on either side of the center the angle that the sound wave bends away from the center before passing through the opening (ii) How is the wavelength related to the frequency of the sound? (Use the following as necessary: f and v. Do not substitute numerical values; use variables only.) F = (iii) Is the wavelength of the sound in air greater than, smaller than, or equal to the wavelength in water? (Note: The speed of sound in air is 343 m/s and the speed of sound in water is 1482 m/s.) greater than smaller than equal to Why? (Select all that apply.) The sound's frequency is independent of the medium. The sound's frequency depends on the medium. The speed of sound is lower in air than in water. The speed of sound is lower in water than in air.
